    • Requested nomination for the new secretary (nomination/interest). Explained duties of the secretary (primarily to compile annual reports for the 2018 and 2019). The secretory will be the chair of the NC1202 by default.

    • The format of annual report is work in progress. The idea is to make progress report format more user friendly and easier for the secretary to compile report in most efficient way. Comments to improve the report format are welcome. Generally, the new format was well received by NC1202 participants.



  • Frank Blecha provided information on feedback from USDA on the submission of NC1202 renewal. Generally, the project was well received and positively reviewed.

  • Margaret Holland provided updates from NIFA.

    • AFRI foundational RFA release expected in Feb, may be in March-2018.

    • There may be only one AFRI challenge (Feb-March-2018) Sustainable Agricultural Systems (CAPs)-2 million/year x 5 years = 10 million

    • There will be AFRI RFA for post-docs/graduate student recruitment.

    • Encouraged participants to carefully review the upcoming Animal Health RFA

    • Invited NC1202 participants to provide stakeholder input (deadline is Dec. 1st 2017). Link to questions: http://www.surveymonkey.com/r/Q6HDGC3

    • for which input is needed: what’s your top priority in food and agricultural research, extension and education and what are the most promising science opportunities for advancement of food and agricultural sciences.

    • Outcomes for 2016 cycle: There were changes in priority areas. Success rate for immune reagents category was 50%. Every category was awarded. However, if there are immune reagents that still needs attention, please let USDA-AFRI know. For 2016: Approx. 26 standard research grants, 3 conference grants and 6 seed grants were awarded.

    • Titles of projects are listed on CREES system (diarrhea in pigs to gut injuries etc. majority of the commodity groups were awarded). The CREES system has all of the updates on prior funding (by topic area, not by year)

    • For 2017-AFRI animal health well-being program is undergoing review. No one has been notified, if you submitted and do not hear either by phone or email by January 30th, email Peter and Margo.

    • US-Ireland research and development program (tripartite) will continue and had 3 awards for 2017.

    • Critical Agricultural Research and Extension (CARE) program is a good opportunity for those engaged in translational research (max of $300,000) for 1 to 3 years. Goal is to develop an implement immediate solution for producers.

    • AFRI foundational (exploratory) grant program will continue. Max $100,000 (1 to 2 year) for proof of concept type of research. Application of new knowledge, new approaches for unsolved problems, paradigm shift, high risk idea etc.

    • Ecology and Evolution of Infectious Diseases. NIFA increased contribution to $ 5 million/year through 2020.

    • Dual Purpose with Dual benefit research ($5 million). NIFA awards 1 to 2 million. Restriction-similarity of problems between animal health and human health. Have to use agricultural animals as a model. Justification in both animal and human health is required. The program will be closing at 5 years (deadline Sept 27, 2018). NC1202 members shared concerns regarding ending of such a unique program that allows overlap between NIH, NIFA and NSF.

    • SBIR (small business innovation research) supports Animal production and Protection area. Phase-1 (100k/8 months), phase-II ($650k/2years). Eligibility limited to businesses with 500/less employees.




 


Discussion:


Meeting called to order at 4:03 pm



  1. New proposal (NC1202) has been approved until 2022.

  2. Currently there are members from 17 institutions. This year, two additional institutions (Oklahoma State and Tennessee State) joined NC1202.

  3. The new multistate group on AMR is in works. Need to find more information about overlap between AMR group and NC1202.

  4. Called for election of new chair. Dr. Isaacson called for motion to elect Dr. Shah as new chair of NC1202, Dr. Rajashekara seconded the motion. Motion was carried unanimously by NC1202 members to elect Dr. Shah as new chair for the next two-year term (2018-19).

  5. Secretary: Does secretory need to be a station representative? Someone mid-career? Dr. Lin proposed Dr. Qiuhong Wang (Ohio State University) as secretory. Dr. Mansfield called for motion, Dr. Linda Saif seconded the motion. Dr. Wang was elected unanimously as new secretary of NC1202 for the two-year term (2018-19).

  6. Topic for next symposium: Gut microbiome. Dr. Saif proposed gut microbiome as a next topic and in general there was strong support by NC1202 members. Need to decide on venue, details of topics etc. The organizing committee was created (Dr. Isaacson as chair of the committee and Drs. Scaria, Saif, and Shahas members of the committee) Following questions were raised as points for further discussion by the committee members.

    1. Do we target people who generally come to CRWAD?

    2. Do we organize with CRWAD as we did for antimicrobial resistance symposium in 2016?

    3. Timing?

    4. Need to communicate with Dr. Banfield (CRWAD) if Sunday for next year has been committed?

    5. Funding? Need to talk with Peter Johnson about funding for meeting not as NC group but as a separate group. What funding opportunities are out there? Conference grant?

    6. Need to also contact industry for sponsorship?

    7. Timeline: The committee needs to decide details of topics, speakers, financial support etc and send out email to our group by early March-2018.




 



  1. Committee will discuss the overall plan and decide on mini-symposium or stand-alone etc.


 



  1. Oral and poster presentations:

    1. In 2017, there are total of 24 abstracts, 4 posters and 7 oral presentations. Judges for oral: Dr. Shah, Rajashekara and Scaria. Judges for poster: Dr. Zhang, Wang and Isaccson.

    2. Awards: Oral (two awards- $250-1st and $150-2nd) and poster (one award-$200). We have $1100 registration fees for 2017 and $1400 from the balance.

    3. Should we have new names for the award. The group unanimously agreed to maintain award names.




Collaboration: Dr. Linda Siaf - we should be prepared to respond to USDA call for collaborative proposal. What if USDA requires matching funds? Dr. Isaccson-USDA may be investing in microbiome research as a topic as there has been some lobbying. We need to wait for the RFA to come out. Dr. Mo Saif- FFAR Foundation for agricultural research may support funding for meetings and can dedicate money to support gap areas. Need to talk to the foundation managers to find out more about how it can support.

Accomplishments

<p><strong>Objective 1. Focus on emerging diseases: We will identify, characterize and develop improved detection and prevention methods related to newly recognized, novel or emerging causes of zoonotic enteric disease and enteric pathogens of food animals.</strong></p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong><em>Salmonella</em></strong></p><br /> <p>&nbsp;</p><br /> <p><strong><em>Shiga toxin-producing E. coli (STEC)and Enterotoxigenic E. coli </em></strong><strong>(ETEC)</strong></p><br /> <p>&nbsp;</p><br /> <ul><br /> <li><strong>Kansas</strong></li><br /> </ul><br /> <p>We fractionated ETEC supernatants using FPLC and determined that ETEC flagellin protects IB from degradation in response to TNF stimulation.</p><br /> <p>&nbsp;</p><br /> <p>We found that EHEC NleB1 glycosylates two GAPDH arginine residues, and that these two residues are essential for GAPDH-mediated activation of TNF receptor-associated factor 2 ubiquitination.</p><br /> <ol start="2"><br /> <li><strong>Nebraska</strong></li><br /> </ol><br /> <p>A study comparing enriched culture, NeoSEEK<sup>TM</sup> STEC Detection and Identification test (NS), and multiplex quantitative PCR on cattle fecal and hide samples indicated no gold-standard method for the detection of enterohemorrhagic <em>E. coli</em> (EHEC) exists.</p><br /> <p>&nbsp;</p><br /> <p>A study testing a repository of STEC strains (n = 70) for resistance to potassium tellurite in broth cultures found the geometric mean MIC for serogroups (n = 10 per serogroup) from highest to lowest to be O111 &gt; O26 &gt; O145 &gt; O157 &gt; O103 &gt; O121 = O45. The MICs for serogroups O45 and O121 were significantly lower than that of O26, O111, and O145, which may explain the relatively low prevalence of these serogroups in studies involving culture-dependent methods.</p><br /> <ol start="3"><br /> <li><strong>Washington</strong></li><br /> </ol><br /> <p>We completed characterization of KsgA (dimethyladenosine trasferase) mutant of Salmonella Enteritidis. We found that KsgA contributes to the cell-envelope integrity of the Salmonella and could be an important target for the development of new antimicrobials and/or immunoprophylactics.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong><em>Campylobacter jejuni</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong>Michigan:</strong></li><br /> </ol><br /> <p>We show that a number of <em>C. jejuni</em> isolates from human enteritis patients colonize and induce colitis in the C57BL/6 IL-10-/- mouse model whereas isolates from human GBS patients colonize with little or no colitis. We have identified the <em>C. jejuni</em> strain dependent immunological mechanisms behind induction of colitis by a gastroenteritis patient derived strain versus induction of an asymptomatic colonization by the GBS patient derived strains. We show that infection of mice with <em>C. jejuni</em> strains from GBS patients, but not from colitis patients, elicits autoantibody production that react against several nerve gangliosides consistent with those seen in human GBS cases.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong><em>Brachyspira</em></strong><strong> <em>hampsonii and Lawsonii intracellularis</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Minnesota</em></strong></li><br /> </ol><br /> <p>RNAseq was used to determine genes expressed in the ilea of pigs challenged with <em>L. intracellularis</em>. Genes associated with cell proliferation and inflammation were the most commonly detected genes with altered expression profiles.</p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <p><strong><em>Coronavirus</em></strong></p><br /> <p><strong>&nbsp;</strong></p><br /> <ol><br /> <li><strong>Illinios:</strong></li><br /> </ol><br /> <p>We have developed a cell model for PEDV infection and replication. The cells retain the genotypes and characteristics of swine intestinal epithelial cells and support PEDV infection. These cells will be useful to isolate PEDV from clinical specimens including stools and intestinal tissues and also for isolation of other swine enteric viruses such as swine delta-coronavirus for which no suitable cell lines exist.</p><br /> <ol start="2"><br /> <li><strong>North Dakota:</strong></li><br /> </ol><br /> <p>A colorimetric method for the quantification of PEDV virus and neutralizing antibodies against PEDV was developed to facilitate high throughput testing in diagnostic laboratories.</p><br /> <ol start="3"><br /> <li><strong>Ohio </strong></li><br /> </ol><br /> <p>We evaluated the Fecal shedding of the virus (porcine, PDCoV), seroconversion, and histopathology in 3-7-old gnotobiotic calves orally inoculated with PDCoV or PEDV. In PDCoV-inoculated calves, acute but persisting fecal viral RNA shedding and PDCoV-specific serum IgG antibody responses were observed, but with a lack of lesions and clinical disease. However, no fecal shedding, seroconversion, histological lesions, and clinical disease were detected in PEDV-inoculated calves.</p><br /> <p>We investigated the prevalence of DCoVs in different populations of wild waterfowl in Ohio, Mississippi, Indiana and Arizona (Mississippi flyway). Five thousand avian cloacal swabs were collected during 2015-2016 to survey for avian influenza virus. To date 500 avian cloacal swab RNA samples were tested for DCoV. Seven of 500 avian samples were positive for DCoVs, Our studies show that DCoVs circulate in wild birds in the US, demonstrating the importance of waterfowl as a reservoir of avian DCoVs.</p><br /> <p>&nbsp;</p><br /> <p>Partial N gene sequence analysis revealed that the newly identified AvDCoVs are most closely related to common-moorhen coronavirus HKU21 (strain HKU21-8295) identified in Hong Kong, China in 2012. This finding suggests that AvDCoVs could have been introduced into the US from China as also suggested for PEDV and PDCoV strains.</p><br /> <p>&nbsp;</p><br /> <p>We have detected the S1 NTD-del type of PEDV for the first time from US swine, indicating that PEDV continues to evolve in pigs and this may be responsible for disease pattern changes.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong><em>Calicivirus</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Ohio</em></strong></li><br /> </ol><br /> <p>We found that human norovirus (HuNoVs) utilizes the same capsid sites to bind to histo-blood group antigens (HBGA) in humans and HBGA-like carbohydrates in lettuce. HuNoVs can be internalized and distributed to edible leaves of lettuce and spinach via contaminated irrigation water from roots.</p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <p><strong><em>Rotavirus</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <p><strong><em>Cryptosporidium</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong>Illinios:</strong></li><br /> </ol><br /> <p>We mined the <em>C. parvum</em> genome and identified genes that encode for rhoptry neck proteins which are known to play a key role in invasion and host-pathogen interactions in other related parasites such as <em>Plasmodium falciparum</em> and <em>Toxoplasma gondii</em>.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong><em>Antimicrobial Resistance (AMR)</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Kansas</em></strong></li><br /> </ol><br /> <p>We employed WGS to detect AMR genes present among <em>Enterococcus faecium</em> strains isolated from swine and cattle probiotics.</p><br /> <p>&nbsp;</p><br /> <p>We identified probiotic products, frequently used in the swine industry, that carry or do not carry AMR.</p><br /> <p>&nbsp;</p><br /> <p>Most <em>E. coli</em> and <em>Enterococcus</em> spp. isolated from fecal samples of piglets fed diets with probiotics alone or in combination with chlortetracycline were multidrug resistant.</p><br /> <p>&nbsp;</p><br /> <p>Cell-penetrating peptides (CPPs) were covalently conjugated to gentamicin and used to target infected cells to kill multiple intracellular Gram-negative pathogenic bacteria, including <em>E.coli</em> K1, <em>S. </em>Typhimurium, and <em>Shigella flexneri</em>.</p><br /> <p>&nbsp;</p><br /> <p>The critical surface characteristics conducive to reducing <em>E. coli</em> adherence to polymeric surfaces were determined.</p><br /> <ol start="2"><br /> <li><strong>Michigan </strong></li><br /> </ol><br /> <p>Infection with antibiotic resistant <em>C. jejuni</em> strains from GBS patients produced both severe Type 1/17 colitis responses when C57BL/6 IL-10<sup>-/- </sup>mice were treated with a broad spectrum antibiotic that decreased complexity and abundance of the gut microbiota. Antibiotic depletion of microbiota was the main factor in inducing enhanced enteric disease and GBS associated phenotypes although the degree of severity was also dependent on the <em>C. jejuni</em> strain. Antibiotic treated infected mice had high numbers of <em>C. jejuni</em> in the apical, basolateral and paracellular junctions of gut epithelium and within cells of the lamina propria, submucosa and lymph nodes indicating increased invasion and translocation from the gut. These results indicate that antibiotic depletion of gut microbiota alters immune responses to <em>C. jejuni </em>in a manner that exacerbates colitis with <em>C. jejuni </em>strains previously shown to promote predominantly Type 2 responses.</p><br /> <ol start="3"><br /> <li><strong>South Dakota</strong></li><br /> </ol><br /> <p>We sequenced the whole genomes of 103 isolates sampled between 1988 and 2003 from wildlife and exotic pets in the United States. 50.48% isolates showed resistance to at least one antibiotic. Resistance against the aminoglycoside streptomycin was most common.</p><br /> <p>&nbsp;</p><br /> <p>We performed metagenome sequencing of microbiome of antibiotic treated and untreated beef cattle. We found that in the treated animals, the abundance of Ruminococcus, Erysipelotrichaceae and Lachnospiraceae which provides colonization resistance to enteric pathogens was reduced.</p><br /> <ol start="4"><br /> <li><strong>Tennessee</strong></li><br /> </ol><br /> <p>We observed that <em>C. jejuni</em> LT inhibitor bulgecin A inhibited the activity of the <em>C. jejuni</em> LT and significantly potentiated &beta;-lactam antibiotic against resistant <em>C. jejuni</em>.&nbsp;&nbsp; The complex structure of the <em>C. jejuni</em> LT with bulgecin A was also obtained, which will facilitate us to identify new lead compounds inhibiting LT using computational docking.</p><br /> <ol start="5"><br /> <li><strong>Wyoming</strong></li><br /> </ol><br /> <p>We conducted surveillance study of E. coli among 1477 European starlings (<em>Sturnus vulgaris</em>) from concentrated animal feeding operations in Colorado (4 farms), Iowa (1 farm), Kansas (6 farms), Missouri (2 farms), and Texas (5 farms). The resistance to &beta;-lactam antimicrobials was common among both MAC-CTX or MAC-CIP isolates tested (as high as 78% of isolates were resistant to ampicillin), we screened for genetic determinants of &beta;-lactam resistance, focusing on predominant class A &szlig;-lactamase genes <em>bla</em><sub>CTX-M</sub>, <em>bla</em><sub>SHV</sub>, <em>bla</em><sub>TEM</sub> and CIT-type AmpCs. CIT-type AmpCs mediated resistance to all &beta;-lactams tested except imipenem (penicillins, &beta;-lactam/&beta;-lactam inhibitors, monobactams, cephalosporins), while <em>bla</em><sub>CTX-M </sub>and <em>bla</em><sub>TEM </sub>were also identified in multiple isolates, primarily mediating resistance to third generation cephalosporins and penicillins, respectively.</p><br /> <ol start="6"><br /> <li><strong>Washington </strong></li><br /> </ol><br /> <p>We have completed a study on surveillance of ESBL producing Gram negative bacteria in backyard poultry in WA State. Our results show that MDR Gram negative bacteria are common in backyard poultry flock environment even in the absence of prior use of antibiotics.</p><br /> <p>&nbsp;</p><br /> <p>We have tested 265 isolates of antibiotic susceptible and resistant Salmonella strains belonging to twelve most-prevalent poultry associated serotypes for inter- and intra-serotype diversity in biofilm formation using 4 different biofilm testing methods. MPPSTs show inter- and intra-serotype differences in the type and amount of biofilm production. Combination of colorimetric microtiter plate assay and congo-red tests significantly improves the detection sensitivity of biofilm in field isolates of MPPSTs. The information will be useful in assessing the role of biofilms in antimicrobial resistance of Salmonella.</p><br /> <p>&nbsp;</p><br /> <p>We have completed an epidemiological investigation on prevalence of invasive and non-invasive Salmonella Typhimurium in Brazil. Our study shows that genotypically distinct lineages of Salmonella Typhimurium ST313 and ST19 are circulating in Brazil. This study should serve as a baseline in studying genetic evolution of S. Typhimurium ST19 in Brazil as well as globally.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>Objective 2. Focus on preventions and interventions: We will develop and improve preventative measures and interventions to reduce the incidence and prevalence of infections of food animals with enteric and foodborne and waterborne pathogens.</strong></p><br /> <p>&nbsp;</p><br /> <p><strong><em>Salmonella </em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Minnesota</em></strong></li><br /> </ol><br /> <p>We confirmed that vaccination of pigs against <em>L. intracellularis</em> reduced shedding of <em>Salmonella enterica</em> in pigs. Further there were associated modification in the composition of the fecal microbiome of these pigs.</p><br /> <p>&nbsp;</p><br /> <ol start="2"><br /> <li><strong>Ohio</strong></li><br /> </ol><br /> <p>We identified four novel small molecule inhibitors of Salmonella serotypes and with restricted effects on other prokaryotes. The antimicrobial efficacy of these compounds was not altered in biofilm-protected Salmonella and the compounds enhanced the in vitro efficacy of existing antibiotics (ciprofloxacin, meromycin, and cefeprim) used to treat Salmonella in poultry and humans. The compounds also reduced Salmonella burden in broiler chicken&rsquo;s ceca when treated for 5 days. Two compounds that reduced Salmonella load in chickens also had minimal impact on the cecal microbiota. <strong><span style="text-decoration: underline;">&nbsp;</span></strong></p><br /> <p>&nbsp;</p><br /> <p>We compared the genomic composition of <em>S. </em>Heidelberg isolated from environmental samples of different breeder farms in the Midwest, US. Whole genome data showed differences in specific metabolic pathways between poultry production system related to horizontal gene transfer (type IV secretion system, conjugative transfer, and phage proteins).</p><br /> <ol start="3"><br /> <li><strong>South Dakota</strong></li><br /> </ol><br /> <p>We developed a gut microbiota culture library from Salmonella free chicken and identified 27 species that inhibit Salmonella. A multi-strain blend from these species were able suppress Salmonella colonization when tested in a germfree chicken model.</p><br /> <ol start="4"><br /> <li><strong>Washington </strong></li><br /> </ol><br /> <p>We have identified new CpG oligodeoxytnucleotide motifs that induce protective innate immune response in day-old chickens against multiple <em>Salmonella </em>serotypes. &nbsp;</p><br /> <p>&nbsp;</p><br /> <p>We completed testing of antimicrobial efficacy of chlorine against twelve most-prevalent poultry associated Salmonella serotypes. We found that different serovars may vary in their susceptibility to chlorine.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong><em>STEC and ETEC</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Minnesota</em></strong></li><br /> </ol><br /> <p>We collaborated with KSU on studies to show that multiepitope vaccines protected pigs against disease after challenge with ETEC and that there were coordinate changes in the ileal microbiome composition in challenged and vaccinated pigs.</p><br /> <ol start="2"><br /> <li><strong>Nebraska</strong></li><br /> </ol><br /> <p>Serogroup O26, O101, O103, O109, O121, O145, O157, and O177 EHEC organisms were detected in recto-anal mucosal swab samples from feedlot steers with all except O121 quantifiable. High concentrations of EHEC were detected in eleven (5.5%) of the steers at least once. These results indicate that in addition to O157, non-O157 EHEC are transiently present in high concentrations in the rectoanal mucosal region of cattle.</p><br /> <p>&nbsp;</p><br /> <p>Hides (n = 800) of market beef cows from two geographically distinct beef packing plants, representing northern or southern regions, were tested for EHEC using the NeoSEEK<sup>TM</sup> STEC Detection and Identification test during four seasons of 2015. Detection of EHEC O26 and EHEC O121 was associated with season. Season and region were associated with detecting EHEC O45 and EHEC O157. Season-by-region interactions were associated with the outcome of detecting EHEC O103, EHEC O111, and EHEC O145. Season, region of origin, and the interaction of these factors affect hide contamination of market beef cattle at slaughter by EHEC, and each serogroup responds to these factors uniquely.</p><br /> <ol start="3"><br /> <li><strong>Ohio</strong></li><br /> </ol><br /> <p>We have identified 11 novel bactericidal compounds against APEC. These compounds were effective against biofilm protected APEC and also on multi-antibiotic resistant APEC strains. The compounds had synergetic effect with antibiotic such as colistin, tetracycline, and ciprofloxacin for APEC. They displayed restricted toxicity on other prokaryotes and to eukaryotic cells. The compounds reduced APEC O78 burden in Caco-2, HD11, human macrophage (THP-1) and Galleria wax moth larvae.</p><br /> <p>&nbsp;</p><br /> <p>We identified 10 compounds that inhibited quorum sensing AI-2 activity of APEC O78 and other APEC serotypes. The compounds showed minimal toxicity and hemolytic activity to chickens red blood cells (RBCs), and significantly affected the survival of APEC O78, O1 and O2 strains in HD-11/ THP-1 macrophages and Caco-2 cells. Most of the compounds significantly reduced biofilm formation and motility of APEC O78. The expression of several QS-regulated, and virulence associated genes of APEC O78 was also differentially affected by these compounds. The compounds also demonstrated good efficacy against APEC infections in vivo in wax moth larvae.</p><br /> <ol start="4"><br /> <li><strong>Wyoming</strong></li><br /> </ol><br /> <p>We have developed transparency-based electrochemical and paper-based colorimetric analytic detection platforms for food and waterborne bacteria detection from a single assay. <em>Escherichia coli</em> and <em>Enterococcus </em>spp., both indicators of fecal contamination, were detected using substrates specific to enzymes produced by each species. Electrochemical detection using stencil-printed carbon electrodes (SPCEs) was found to provide optimal performance on inexpensive and disposable transparency film platforms. Using SPCEs, detection limits for electrochemically active substrates, PNP, ONP, and PAP were determined to be 1.1, 2.8, and 0.5 &mu;M, respectively. Low concentrations (10<sup>1</sup> CFU/mL) of pathogenic and nonpathogenic <em>E. coli</em> isolates and (10<sup>0</sup> CFU/mL) <em>E. faecalis</em> and <em>E. faecium</em> strains were detected within 4 and 8 h of pre-enrichment.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong><em>Campylobacter jejuni</em></strong></p><br /> <ol><br /> <li><strong><em>Iowa</em></strong></li><br /> </ol><br /> <p>We have completed a longitudinal study on 15 commercial broiler farms (as part of the same integrated production system) including 461 flocks reared in 53 houses for up to 10 consecutive production cycles for <em>Campylobacter</em> presence. The <em>Campylobacter</em> prevalence varied remarkably among farms, houses and flocks examined, with some houses/farms testing consistently negative while others being always positive over the entire sampling period. A risk factor analysis found that <em>Campylobacter</em> positivity/high prevalence was associated with increased feed conversion, increased adjusted prime cost, and decreased paw quality/increased percent hock burnt. Conversely, the variables of increasing average weight, increasing average daily gain, increasing feed conversion adjustment factor values, practice of litter treatment with different chemicals, increasing house temperature, increasing air litter temperature, the condition of air ammonia level (being less than 25 ppm) and litter amendment being used at proper rate were all associated with <em>Campylobacter</em> negativity/low prevalence.</p><br /> <p>&nbsp;</p><br /> <p>We investigated whether the intestinal microbiota composition correlated with the observed <em>Campylobacter</em> colonization status between the aforementioned broiler farms using a fecal transplantation-<em>in vivo</em> challenge study and 16S rRNA gene-based microbiota analysis. Analysis of <em>Campylobacter</em>-positive (n= 90) vs. &ndash;negative (n= 90) intestinal contents revealed differences in the microbiome compositions.</p><br /> <ol start="2"><br /> <li><strong><em>Michigan</em></strong></li><br /> </ol><br /> <p>BALB/c and C57BL/6 mice given&nbsp;C. jejuni&nbsp;displayed evidence of GBS autoimmunity, with varied immune responses and disease outcomes BALB/c IL-10<sup>-/-</sup>&nbsp;mice infected with&nbsp;<em>C. jejuni</em>&nbsp;11168 exhibited the lowest survivorship, the most severe gross pathology at necropsy and highest grade histopathologic lesions in the ileocecocolic junction, and the highest mean plasma concentrations of anti-<em>C. jejuni</em>&nbsp;IgG1, IgG3, IgG2b, and IgG2a/c antibodies. Significant increases in GM1 and GD1a anti-ganglioside antibody isotypes varied between treatment groups, although no significant differences in macrophage infiltration into lumbar dorsal root ganglia were seen. Immunohistochemical assessment of&nbsp;<em>C. jejuni </em>abundance and localization in the ileocecocolic junction and evaluation of IFN-&gamma;, IL-4, and IL-17 cytokine production in colon tissue reflecting the local adaptive immune response are underway. These findings provide a new murine model of GBS following&nbsp;<em>C. jejuni</em>&nbsp;infection designed to examine differences in pathogenesis based on host genotype and infecting&nbsp;<em>C. jejuni</em>&nbsp;strain.</p><br /> <ol start="3"><br /> <li><strong><em>Ohio</em></strong></li><br /> </ol><br /> <p>We found that pre-treatment of HT-29 human colonic cells with the probiotic EcN significantly affect C. jejuni invasion (~ 2.5 log reduction) and no intracellular <em>C. jejuni</em> were recovered. EcN positively affected the expression of genes that are involved in enhanced intestinal barrier function, decreased cell permeability, and increased tight junction integrity, cell proliferation and cellular immunity.</p><br /> <p>&nbsp;</p><br /> <p>We showed that <em>C. jejuni</em> exhibited enhanced chemoattraction to and respiration of formate in comparison to other organic acids. Formate also significantly increased <em>C. jejuni</em>&rsquo;s growth, motility, and biofilm formation under microaerobic (5% O2) conditions. However, formate reduced oxidase stress under microaerobic conditions as well as aerotolerance and biofilm formation under ambient oxygen conditions. The expression of genes encoding the ribonucleotide reductase (RNR) and proteins that facilitate the use of alternative electron acceptors were increased in the presence of formate.</p><br /> <ol start="4"><br /> <li><strong>Tennessee</strong></li><br /> </ol><br /> <p>We continued to develop and assess enterobactin (Ent) antibody-based immune intervention strategies. The Ent conjugate vaccine was used to immunize rabbits, successfully generating Ent specific antibodies.&nbsp; We also immunized layers with the Ent conjugate vaccine, which triggered strong immune response and led to the production of hyperimmunized egg yolk powder.&nbsp;</p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <p><strong><em>Brachyspira hampsonii and Lawsonii intracellularis</em></strong></p><br /> <p><strong><em>Coronavirus </em></strong></p><br /> <p><strong>&nbsp;</strong></p><br /> <ol><br /> <li><strong>Illinios:</strong></li><br /> </ol><br /> <p>For enteric viruses, type III interferons seem to play a major role to protect from infection in the early stage of infection. We have developed an assay system to monitor the production of type III interferon by PEDV in cells.</p><br /> <p>&nbsp;</p><br /> <p>We have discovered het PEDV has the ability to counteract the host innate immune response by suppressing type III production such that PEDV is not readily eliminated and instead survive for an extended duration of infection. We have also identified viral protein responsible for this interferon antagonism.</p><br /> <ol start="2"><br /> <li><strong>North Dakota</strong></li><br /> </ol><br /> <p>A proprietary process for the development of safe and efficacious rapid-response vaccines against RNA viruses, such as PEDV, was developed and tested. The process is intended to be a hybrid between inactivated and attenuated vaccines, such that the safety and efficacy advantages are combined. Testing of the vaccine candidate in 3-4 week-old pigs showed that strong anti-spike protein specific antibodies were elicited by vaccination. Vaccinated pigs were completely protected against virulent challenge, while all unvaccinated controls showed signs of the disease. Hence, the developed method showed significant promise for rapid-response vaccine development and for improving the safety of current autogenous vaccines</p><br /> <ol start="3"><br /> <li><strong>Ohio</strong></li><br /> </ol><br /> <p>We tested the effects of VitA supplementation in gilts on mucosal immune responses and the gut-mammary-sIgA axis to boost lactogenic immunity and passive protection of nursing piglets against PEDV challenge. The mortality rate of PEDV-challenged piglets of PEDV+VitA gilts was 6.25% compared with 33.3% and 94.3% for PEDV and Mock litters, respectively. Piglets born to PEDV+VitA gilts had lower diarrhea scores at multiple post-challenge days (PCD). PEDV-specific IgA ASC appeared earlier in peripheral blood [post-inoculation day (PID) 6-8] of PEDV+VitA gilts compared with PEDV gilts (PID 12-17) and PEDV+VitA gilts had higher frequencies of IgA<sup>+&nbsp;</sup>and IgA<sup>+</sup>&beta;7<sup>+</sup>&nbsp;mononuclear cells in blood at PID 6-8. In colostrum, milk and serum, PEDV+VitA gilts had higher mean PEDV neutralizing antibody titers and milk PEDV-specific IgA ASC compared with PEDV gilts at various piglet PCDs.</p><br /> <p>&nbsp;</p><br /> <p>We are identifying viral genes related to PEDV virulence in pigs and designing efficacious live attenuated PEDV vaccine candidates using Vero cell-adaptation method and reverse genetics technology.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong><em>Calicivirus </em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Kansas</em></strong></li><br /> </ol><br /> <p>We reported the structure-based design of dipeptidyl compounds against norovirus 3C-like proteases and demonstrated they are highly effective in vitro and in vivo.</p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <p><strong><em>Rotavirus</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Ohio</em></strong></li><br /> </ol><br /> <p>We evaluated the effect of ciprofloxacin [alone or co-administered with the probiotic <em>E. coli</em> Nissle 1917 (EcN)] on intestinal epithelial cell (IEC) numbers and human rotavirus (HRV) infection in a germ-free (GF) or defined commensal microbiota (DM)-associated neonatal pig model. Irrespective of the microbiota status, the ciprofloxacin-treated, HRV infected group had more severe diarrhea, which unexpectedly, coincided with decreased HRV shedding. Interestingly, ciprofloxacin treatment significantly reduced numbers of SOX9+ on intestinal epithelial stem cells (IESC) and goblet cells in the ileum of DM-colonized or GF piglets on day 21 following treatment. In contrast, EcN treatment decreased HRV diarrhea and shedding which coincided with increased numbers of SOX9+ IESCs and goblet cells in piglets with or without ciprofloxacin treatment.</p><br /> <p>&nbsp;</p><br /> <p>Using commensal microbiota (DM)-associated neonatal pig model, after six days of CIP treatment (DMF+CIP), significantly decreased aerobic and anaerobic bacteria counts especially in jejunum (P&lt;0.001).&nbsp; EcN treatment enhanced the bacterial diversity of DMF species and increased the proportion of&nbsp;B. longum&nbsp;especially in jejunum and mitigated adverse impacts of antibiotic use during acute-infectious diarrhea.</p><br /> <p>&nbsp;</p><br /> <p>We evaluated the effects of childhood protein malnutrition on adaptive immunity and tryptophan metabolism. After HRV infection, protein-deficient pigs had decreased HRV antibody titers and total IgA concentrations, systemic T helper and cytotoxic T lymphocyte frequencies, and serum tryptophan and angiotensin I-converting enzyme 2. Additionally, deficient-diet pigs had impaired tryptophan catabolism post infection compared with sufficient-diet pigs. Further, tryptophan supplementation increased the frequencies of regulatory T cells in pigs on both the sufficient and the deficient diets.</p><br /> <p>&nbsp;</p><br /> <p>We have established porcine small intestinal (ileal) enteroids (IE) derived from neonatal piglets, and optimized culture media composition and IE propagation/differentiation regimens. We successfully infected IE cultures with HRV Wa strain resulting in increased infectious titers of at least 1 log.</p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <p><strong><em>Norovirus</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <p><strong><em>Cryptosporidium</em></strong></p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong>Illinios:</strong></li><br /> </ol><br /> <p>We have identified novel rhoptry neck proteins in <em>Cryptosporidium parvum</em>.

The members agreed that the NC1202 should make an effort to get additional funding to support awards in the future



  1. Whether NC1202 uses the CRWAD Abstract submission and Preseria systems


Members unanimously voted not to use the systems because most data are at pre-publication stage.



  1. On-site registration option from 2019 onwards: CRWAD organizers have initiated online registration and offered this option for NC1202 members. The members generally agree that online registration will help avoid physical money transactions, make the process more efficient and reduce the workload of chair and the secretary. Only current members will be able to register online. The chair will communicate with CRWAD organizers to initiate process of online registration starting from 2019.

    1. Need to come up with a short description for NC1202 for public viewing online.

Accomplishments

<p><strong>Objective 1. Focus on emerging diseases: We will identify, characterize and develop improved detection and prevention methods related to newly recognized, novel or emerging causes of zoonotic enteric disease and enteric pathogens of food animals.</strong></p><br /> <p><strong>&nbsp;</strong></p><br /> <ol><br /> <li><strong><em>Salmonella</em></strong></li><br /> </ol><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong>Washington</strong></li><br /> </ol><br /> <ul><br /> <li>We have sequenced complete genome of ciprofloxacin resistant <em>Salmonella</em> enterica subsp. enterica Serovar Kentucky Sequence Type 198 Strain, PU131, Isolated from a Human Patient in Washington State.</li><br /> </ul><br /> <p>&nbsp;</p><br /> <ol start="2"><br /> <li><strong>South Dakota</strong></li><br /> </ol><br /> <ul><br /> <li>We established a baseline of Salmonella prevalence in porcine lymph nodes (LNs) across the USA in 21 commercial pork harvest facilities, representing northern (n=12) or southern (n=9) geographical regions. Overall, 6.4% of market hog and 37.0% of sow samples in the northern region and 13.0% of market hog and 4.8% of sow samples in the southern region were Salmonella positive. In both regions, samples from conventionally chilled carcasses returned more (P &lt; 0.05) positive results. Overall, the higher rate of Salmonella prevalence in northern sows (P&lt;0.05) warrants further investigation.</li><br /> <li>A total of 23 Salmonella serotypes were detected in 50 (19%) of 261 retail fresh ground meat samples collected from grocery stores in the Brookings, South Dakota. These included 2 (2%) of 115 ground turkey samples, 6 (14%) of 42 chicken samples, and 42 (40%) of 104 ground pork samples. S. Enteriditis (5) was the most predominant in chicken meat. In ground pork, the most common serotypes included monophasic variant of Typhimurium (n=5), Uganda (5), Anatum (4), Derby (3), Infantis (3), and London (3). A total of 25 isolates (56%) were susceptible to all 14 antibiotics tested, 11 (24%) resistant to 1 antibiotic, 4 (9%) resistant to 2 antibiotics, 1 (2%) resistant to 3 antibiotics, 2 (4%) resistant to 4 antibiotics, 1 (2%) resistant to 8 antibiotics, and 1 (2%) resistant to 10 antibiotics. The most common antibiotic resistances observed included streptomycin (15), tetracycline (11), and sulfisoxazole (7).</li><br /> <li>Radhey Kaushik&rsquo;s group developed and characterized immortalized bovine ileal epithelial cell line (BIEC) by human telomerase encoded reverse transcriptase (hTERT), simian-virus 40 large T antigen (SV40) and human papilloma virus E6/E7 protein (HPV E6/E7). Our study shows that BIEC cells may serve as a good model for studying the intestinal innate immune responses.</li><br /> </ul><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Shiga toxin-producing E. coli (STEC) and Enterotoxigenic E. coli </em></strong><strong>(ETEC)</strong></li><br /> </ol><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong>Kansas</strong></li><br /> </ol><br /> <ul><br /> <li>We isolated novel N-acyl homoserine lactone-producing bacteria from cattle rumen that may impact STEC biology. We detected and quantified the seven major serogroups of STEC on hides of cull dairy, cull beef, and fed beef cattle at slaughter. We performed Bayesian estimation of true prevalence, sensitivity, and specificity of three diagnostic tests for detection of <em>Escherichia coli </em>O157 in cattle feces.</li><br /> </ul><br /> <p><strong>&nbsp;</strong></p><br /> <ol start="2"><br /> <li><strong>Nebraska</strong></li><br /> </ol><br /> <ul><br /> <li>The efficacy of three different agar culture media for detection of USDA-FSIS adulterant-type Shiga toxin-producing <em>Escherichia coli</em> (STEC) in beef was evaluated.</li><br /> </ul><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Campylobacter jejuni</em></strong></li><br /> </ol><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Brachyspira</em></strong><strong> <em>hyodysenteriae and Lawsonii intracellularis</em></strong></li><br /> <li><strong>Minnesota</strong></li><br /> </ol><br /> <ul><br /> <li>We performed a study to evaluate whether intestinal epithelial cell lines proliferate when infected by <em> intracellularis</em> at high or low passages, and to determine whether culture of various cell lines under conditions of reduced growth factors would facilitate detection of cellular proliferation <em>in vitro</em> induced by <em>L. intracellularis</em>.</li><br /> <li>We have developed Enteroids as an infection model for&nbsp;<em> intracellularis</em>using enteroids, both from mouse and pig intestines.&nbsp;</li><br /> <li>We evaluated the sensitivities and specificities of two commercial blocking ELISA and the Immunoperoxidase Monolayer Assay using serum samples from pigs with known <em> intracellularis</em> infection status, including positive and negative status, and vaccinated animals. The two serological assays showed a correlation of 0.80 using pig sera. The correlation coefficient and Kappa coefficient improved for both tests after omitting serum sets from aged and vaccinated pigs.&nbsp;</li><br /> <li>We developed and evaluated two different ELISA tests using whole cells and recombinant proteins to detect antibodies (both IgG and IgA) of <em> hyodysenteriae</em> in sera, feces and colon scrapings of pigs.</li><br /> </ul><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Coronavirus</em></strong></li><br /> <li><strong>Illinios:</strong></li><br /> </ol><br /> <ul><br /> <li>We developed and characterized line of porcine intestinal epithelial cells as a cell model for PEDV replication. Our study for the first time provides the evidence that the porcine enteric virus PEDV downregulates and evades the IRF1-mediated type III IFN responses by reducing the peroxisomes.</li><br /> </ul><br /> <p><strong>&nbsp;</strong></p><br /> <ol start="2"><br /> <li><strong>Ohio </strong></li><br /> </ol><br /> <ul><br /> <li>We investigated whether IPEC-J2 cells are susceptible to porcine deltacoronavirus (PDCoV) infection. PDCoV antigen was detected in the cells showing Cytopathic effects (CPE) in these cells. By double immunofluorescent and TUNEL staining, most PDCoV antigen-positive IPEC-J2 cells failed to show TUNEL-positive signals, indicating that PDCoV-infected IPEC-J2 cells may not undergo apoptosis, but rather necrosis, similar to necrotic cell death of infected enterocytes <em>in vivo. </em></li><br /> <li>We investigated the prevalence of deltacoronavirus (&delta;-CoV) &gamma;-CoV in wild migratory terrestrial and aquatic birds in Arkansas, Illinois, Indiana, Maryland, Mississippi, Missouri, Ohio, Tennessee and Wisconsin in 1,236 avian cloacal swabs during 2015-2017 using genus-specific reverse transcription-PCR assays. Unlike previous reports from Asia, our study show that in the US, &gamma;-CoVs are more prevalent than &delta;-CoVs. The prevalence of &delta;- and &gamma;-CoVs in aquatic birds was 1.34% and 6.3%, respectively, compared to only 0.6% and 0% in terrestrial birds. We also show that there is increased genetic heterogeneity of &delta;-CoVs.</li><br /> </ul><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Calicivirus</em></strong></li><br /> <li><strong>Ohio</strong></li><br /> </ol><br /> <ul><br /> <li>We are investigating which amino acid residues of the capsid protein of human norovirus (HuNoVs) are critical for the binding to histo-blood group antigen (HBGA)-like carbohydrates in lettuce.</li><br /> </ul><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Rotavirus</em></strong></li><br /> <li><strong>Ohio</strong></li><br /> </ol><br /> <ul><br /> <li>We found that a significantly higher prevalence of Rotavirus C (RVC) in litters with diarrhea born to gilts compared with those born to multiparous sows. Using RVC-VLP ELISA we demonstrated that gilts (first parity animals) with diarrheic litters had significantly lower RVC Ab titers in milk (but not in serum) compared with those of sows with healthy litters.</li><br /> </ul><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Cryptosporidium</em></strong></li><br /> <li><strong>Illinois</strong></li><br /> </ol><br /> <ul><br /> <li>We have established two technological approaches (morpholino oligomer-based and CRISPR CAS-based approaches) to genetically manipulate <em>Cryptosporidium parvum</em> (<em> parvum</em>) and robust animal model systems to study the parasite. We mined the <em>C. parvum</em> genome and identified genes that encode for rhoptry neck proteins.</li><br /> </ul><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Giardia</em></strong></li><br /> <li><strong>Michigan</strong></li><br /> </ol><br /> <ul><br /> <li>We determined the prevalence of <em>Giardia</em> in three populations of dogs in Mid-Michigan by molecular diagnostic assays and 16S rDNA sequencing of the fecal microbiome. One hundred dogs were enrolled into the study. The majority of dogs presenting to the primary care clinic were Giardia negative and not experiencing diarrhea (66%). Five percent of Giardia positive dogs had diarrhea while 8% positive dogs did not show diarrhea. 21% of dogs had diarrhea that was not explained by the presence of <em>Giardia</em> or the presence of the enteric pathogens. One diarrhea positive, <em>Giardia</em> negative dogs had <em>Helicobacter </em>spp<em>. </em>6 diarrhea negative and <em>Giardia </em>negative were positive for either <em>Campylobacter </em> or <em>Helicobacter </em>spp. One dog had both <em>Campylobacter </em>spp. and <em>Helicobacter </em>spp.</li><br /> </ul><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Antimicrobial Resistance (AMR)</em></strong></li><br /> <li><strong>Michigan </strong></li><br /> </ol><br /> <ul><br /> <li>We found that antibiotic treatment enhanced the frequency and severity of colitis and exacerbated anti-ganglioside antibody responses after infection of a mouse model with antibiotic resistant <em>Campylobacter jejuni</em>. These results were <em>jejuni</em> strain specific. We found that antibiotic depletion of gut microbiota was another critical factor in the manifestation of severe enteric disease and Guillain Barr&eacute; syndrome (GBS) associated phenotypes in this mouse model.</li><br /> </ul><br /> <p>&nbsp;</p><br /> <ol start="2"><br /> <li><strong>Tennessee</strong><br /> <ul><br /> <li>We performed genomics analysis of 20 diverse strains of <em>Salmonella </em>Indiana which showed both plasmid and chromosomal integon I exist S. Indiana. The unique long chromosomal class I integron (7.8-kb), which is not linked to SGI1, shares extremely high similarity to that identified in a MDR <em> coli</em> plasmid.</li><br /> <li>Using controlled systems, we observed the MCR-1 (colistin resistance marker) confers cross-resistance to bacitracin, a popular in-feed antibiotic used in food animals.</li><br /> <li>We show crystal structures of the soluble LT from <em> jejuni</em> with and without bulgecin A inhibitor in the active site, providing insights into future LT inhibitor development for C. jejuni.</li><br /> </ul><br /> </li><br /> </ol><br /> <p><strong>&nbsp;</strong></p><br /> <ol start="2"><br /> <li><strong>Wyoming</strong><br /> <ul><br /> <li><em> coli</em> isolates (n = 39) resistant to cephems and cephems/fluoroquinolones were subjected to whole genome sequencing (PacBio/HiSeq sequencing) and phylogenetic analyses on the basis of identical antibiograms (18 different antibiotics tested) and presence in the feces of both raccoons and cattle on multiple farms. We show that there is a genetic conservation between AMR isolates from cattle and wildlife suggesting a complex AMR livestock ecology that has inputs from multiple sources.</li><br /> <li>We have expanded the detectable proteome in antibiotic-resistant bacteria by developing an offline LC protein separation/fractionation prior to MALDI-ToF-MS analysis and applied it for the analysis of antibiotic-resistant <em> coli</em> isolates. Using LC-MALDI-ToF-MS in conjunction with supervised PCA, we identified protein biomarkers which exhibited the strongest correlation to &beta;-lactam resistance among the <em>E. coli </em>tested, namely resistance mediated by the <em>bla</em><sub>CMY-2</sub> gene (encoding AmpC-type &beta;-lactamase) in the incompatibility plasmid complex A/C (IncA/C).</li><br /> <li>We conducted the first nationwide survey of AMR phenotypes in indicator bacteria from composite fecal samples collected from 52 dairy farms in located within 7 administrative districts of Kosovo. Isolation and characterization of <em> coli</em> (n = 165) and <em>Enterococcus</em> spp. (n = 153). <em>E. coli</em> and <em>Enterococcus </em>spp. isolated using sub-MIC of cefoxitin, ciprofloxacin, or erythromycin were typically resistant to at least one and often multiple antibiotics, including &beta;-lactams, quinolones, sulfonamides, phenicols, and tetracyclines for <em>E. coli</em> isolates and macrolides, tetracyclines, and rifamycins for enterococci isolates.</li><br /> </ul><br /> </li><br /> </ol><br /> <p><strong>&nbsp;</strong></p><br /> <ol start="3"><br /> <li><strong>Washington </strong></li><br /> </ol><br /> <ul><br /> <li>We have completed identification and characterization of 143 MDR Gram negative bacteria isolated from backyard poultry flocks in WA State.

The effect of vaccination was dependent upon challenge with <em>L. intracellularis</em>, which suggests that apart from changes in the microbiome an immune response may also be involved in these observations.</li><br /> </ul><br /> <p>&nbsp;</p><br /> <ol start="2"><br /> <li><strong>Ohio</strong></li><br /> </ol><br /> <ul><br /> <li>We identified 4 novel small molecule inhibitors of <em>Salmonella</em> serotypes and with restricted effects on other prokaryotes at 200 &mu;M. The antimicrobial efficacy of these compounds was not altered in biofilm-protected Salmonella and the compounds enhanced the in vitro efficacy of antibiotics (ciprofloxacin, meromycin, and cefeprim). The compounds also reduced Salmonella burden in broiler chicken&rsquo;s ceca when treated for 5 days. Further, 2 compounds that reduced <em>Salmonella</em> load in chickens also had minimal impact on the cecal microbiota.</li><br /> <li>We compared the genomic composition of Heidelberg isolated from environmental samples of different breeder farms in the Midwest, US and show that there are differences in specific metabolic pathways between poultry production system related to horizontal gene transfer (type IV secretion system, conjugative transfer, and phage proteins).</li><br /> <li>We analyzed the efficacy and antimicrobial characterization of different known probiotic bacteria against <em>Salmonella</em> infections <em>in vitro</em>. The <em>Salmonella</em> inhibiting ability of the probiotics were tested in various coculture <em>in vitro</em> assays to determine the efficacy of their inhibition.

Expression of KsgA-antagnost (ksgAE66A) exacerbated the cell-envelope fitness defects, resulting in impaired S.

This study shows that KsgA contributes to cell-envelope fitness and opens new avenues to modulate cell-envelopes via use of KsgA-antagonists.</li><br /> </ul><br /> <p><em>&nbsp;</em></p><br /> <ul><br /> <li>We completed molecular characterization of <em>Salmonella</em> pathogenicity island 13 (SPI-13) mutants of <em>Salmonella</em>. SPI-13 is required for efficient utilization of two micronutrients, namely, d-glucuronic acid (DGA) and tyramine (TYR), as sole sources of carbon and/or nitrogen. By systematic deletion of the individual gene(s), we have identified specific genes within SPI-13 that are required for efficient utilization of DGA and TYR as sole nutrient sources. We completed comparative genomics analysis of the SPI-13 locus from 247 Salmonella strains belonging to 57 different serovars to show that SPI-13 genes specifically involved in the metabolism of DGA and TYR are highly conserved in Salmonella enterica.</li><br /> </ul><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>STEC and ETEC</em></strong></li><br /> <li><strong><em>Kansas</em></strong></li><br /> </ol><br /> <ul><br /> <li>We refined the efficacy of an ETEC vaccine candidate named Skp by expressing this protein in immunogenic, non-toxic, bacterial outer membrane vesicles.

These GI&rsquo;s considerably reduced the APEC induced mortality of chickens, APEC load and APEC lesions severity in chickens. These GI&rsquo;s affected the APEC cell membrane and were effective against multiple APEC serotypes including those are antibiotics resistant and on APEC biofilm. We also identified two probiotics and their derived small peptides (P-1, P-2, and P-3) with antimicrobial activity against APEC.</li><br /> <li>We identified 10 quorum sensing inhibitors (QSI) that inhibited the AI-2 activity of APEC O78. Seven were tested in one-week old broiler chickens for their efficacy against APEC O78. We found that treatment of the infected chickens with QSI-5 and QSI-10 resulted in 100% and 75% reduced mortality respectively; while QSI-2 and QSI-8 reduced mortality up to 50% in comparison to Additionally, QSI-5 and QSI-10 reduced the pathological lesion (&gt;85%) in different organs compared to control.

After the inoculation, natural carriage of FQ-R <em>Campylobacter</em> decreased, which was accompanied by increase of FQ-S <em>Campylobacter</em>. However, after enrofloxacin treatment was given, the calves were recolonized by FQ-R <em>Campylobacter</em>. Prior to inoculation, the calves were predominantly colonized by FQ-R cluster ST982. After inoculation, the predominant genotypes changed to FQ-S clusters C ST929 and D ST61. Following the treatment with enrofloxacin, the primary genotypes shifted to FQ-R clusters A ST982 and B ST922.

However, EcN, when delivered orally to chickens, survives modestly under low gastric pH and do not persist long in the gut. Therefore, we formulated EcN microcapsules using FDA approved alginate and chitosan nanoparticles. The EcN microcapsules displayed; better survivability under simulated harsh gastrointestinal conditions, sustained EcN release, and enhanced antimicrobial activity against <em>Campylobacter</em>.&nbsp;&nbsp;&nbsp;</li><br /> <li>The chickens were vaccinated with six Recombinant Attenuated <em>Salmonella </em>Vaccines (RASV-Cj strains-pG8R-86, pG8R-88, pG8R-89, pG8R-90, pG8R-102, and pG8R-128) and later challenged with a cocktail of 5 <em> jejuni</em> strains from a chicken source.

Protein deficient AttHRV vaccinated piglets had altered intestinal microbiota composition, decreased microbiota diversity in intestinal tissues, and increased microbiota diversity in systemic tissues. Deficient-HIFM pigs tissues were characterized by lower F:B ratios. In the AttHRV vaccinated pigs, protein deficiency resulted in a decreased proportion of Firmicutes (Turicibacter spp. that stimulates immune function), concomitant with increased Proteobacteria (Proteus spp.) compared with piglets on sufficient diet.</li><br /> </ul><br /> <p>&nbsp;</p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Norovirus</em></strong></li><br /> </ol><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Adenovirus Serotype 36 in Obesity induction </em></strong></li><br /> </ol><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong>Tennessee</strong></li><br /> </ol><br /> <ul><br /> <li>We investigated the potential synergistic effect of a high-fat (HF) diet and infection by an adipogenic virus (e.g. human adenovirus serotype 36, Had-36), the two causal factors in obesity induction using rat model.

Impact Statements

  1. A. Kansas 1. We further refined the efficacy of a colonization factor-independent ETEC vaccine antigen. 2. Solving the NleB and SseK crystal structures provided a means for the development of anti-virulence therapies targeting E. coli and Salmonella. 3. We established more precise estimates for the prevalence of non-O157 STEC in beef cattle. 4. We identified new PEDV vaccine candidates. B. Illinois 1. The results obtained from this project will provide new directions in the study of enteric viruses and parasites that can be exploited for the development of novel drugs and vaccines for treating or preventing the organisms in food animals. C. Minnesota 1. Effects of Lawsonia intracellularis infection on the proliferation of different mammalian cell lines. Our findings provide data to support and expand previous subjective observations of the absence of in vitro proliferation caused by L. intracellularis in cell cultures and confirm that cell lines infected by L. intracellularis fail to serve as adequate models for understanding the cellular changes observed in proliferative enteropathy-affected intestines. 2. Enteroids as a model for Lawsonia pathogenesis. Our mouse and pig enteroid infection models may be useful in determining mechanisms of the pathogenesis of L. intracellularis, as well as other enteric pathogens, and potential treatment options. 3. Evaluation of two serological assays for Lawsonia intracellularis antibodies. We evaluated two serological assays for L. intracellularis, and this information will be useful for conducting disease surveillance in pig herds. For comparative purposes, an approximation of endpoint titer can now be made by converting the ELISA PI value to an endpoint titer using a standard curve. 4. Development of a serologic assay using recombinant proteins and whole cell antigen for detection of IgG and IgA against Brachyspira hyodysenteriae. We have developed and evaluated serology assays for B. hyodysenteriae that detect IgG antibodies in sera and IgA antibodies in colonic scrapings. 5. Vaccination against Lawsonia intracellularis decreases shedding of Salmonella enterica serovar Typhimurium in co-infected pigs and alters the gut microbiome. The use of vaccination against L. intracellularis to control S. enterica is a novel and promising new tool that is much needed for controlling S. enterica in pig herds as well as improving food safety, and may be an alternative to the use of antimicrobials. 6. The effects of zinc amino acid complex supplementation on the porcine host response to Lawsonia intracellularis infection. Our L. intracellularis challenge study demonstrated that a zinc-amino acid complex aids the host in responding to L. intracellularis infection and may be a new approach to help minimize negative effects of disease. 1. Impact of vaccination on transmission of Lawsonia intracellularis in pigs. This study demonstrated adequate efficacy of both available vaccination protocols, reducing shedding after contact with infectious animals. However, neither vaccination protocol significantly decreased transmission rate. From a field perspective, these results stress the importance of implementing vaccination programs at the system level, not site-specific interventions. D. Wyoming 1. Improved understanding of antimicrobial resistance in wildlife associated with concentrated animal feeding operations. 2. Enhanced diagnostics of antimicrobial resistant foodborne pathogens using mass spectrometry E. Washington 1. Our research provides evidence that KsgA contributes to the cell-envelope integrity of the Salmonella and could be an important target for the development of new antimicrobials or immunoprophylactics. 2. Our research shows that SPI-13 plays an important role in nutrient acquisition of Salmonella and that FDA approved anti-metabolites can be used as non-antibiotic alternatives to inhibit metabolic pathways of Salmonella thereby inhibiting Salmonella growth. 3. Complete genome sequence of ciprofloxacin resistant strain of S. Kentucky will aid dissecting epidemiological analysis of globally disseminated strains of S. Kentucky ST198. F. Iowa 1) Commercial cattle harbor genetically diverse FQ-R Campylobacter. 2) Single dose treatment with enrofloxacin enriches pre-existing FQ-R populations, but has little effect on de novo selection of FQ-R Campylobacter. 3) Important insights are provided for better understanding the epidemiology and management of FQ-R Campylobacter in cattle, and thus for the mitigation of spread of resistance to the environment and public. G. Nebraska 1. The efficacies of culture-based methods for detection of EHEC were determined to guide development of best practices for detection of Shiga toxin-producing E. coli (STEC) in beef. 2. Cattle fecal and hide EHEC prevalence and concentration data were generated and incorporated into a quantitative microbial risk assessment model with the goal of reducing the occurrence and public health risks of these organisms in beef. 3. A fimbria-toxoid candidate vaccine for post-weaning enterotoxigenic E. coli (ETEC) in swine was developed. G. Ohio 1. Our study indicates that the susceptibility of IPEC-J2 cells to PDCoV infection supports their usefulness to characterize the interactions of enterocytes with PDCoV. 2. Our study suggests that serotonin release from EC cells (increased serotonin levels) into the gut submucosa might occur early PEDV post-infection to stimulate the vagal afferent neurons, followed by vomiting. Serotonin might be involved in the mechanisms related to vomiting in PEDV-infected piglets. 3. Development of efficacious vaccines will directly promote the control and prevention of PEDV, thus contribute to pig health and help maintain a sustainable pork industry. 4. Understanding the impact of stage of gestation at PEDV infection or exposure on maternal immunity will allow more precise maternal vaccination protocols to target the time when the animal is most immunologically responsive. Optimizing vaccine efficacy for gestating and lactating animals will enhance lactogenic immunity in neonates and decrease morbidity and mortality associated with neonatal enteric disease. 5. Deltacoronaviruses (PDCoV and ADCoV). Our study indicates the potential ability of the emerged PDCoV and other DCoV isolates from birds or small mammals to infect different animal species. Although there is no evidence that porcine or avian DCoVs are infectious to humans, their potential threat to public health remains uncertain due to relatively high genetic heterogeneity (and therefore genomic plasticity) of DCoVs and likely ongoing adaptation to their current hosts. 6. Our data indicate that piglets born to gilts are at increased risk of developing clinical disease following postnatal infections with endemic or re-emerging enteric viruses. Efficacious vaccines and other measures are needed to boost lactogenic immunity in guilts. 7. Our findings demonstrate that protein deficiency negatively affects neonatal immune function, alters intestinal microbiome and compromises HRV vaccine efficacy. These findings are applicable to human and swine health and indicate that adequate nutrition is critical for the efficient control and prevention of infectious diseases. 8. Our finding showed that abundance and diversity of microbiota is different in vaccinated protein-deficient and -sufficient diet fed piglets which in turn contributes to poor efficacy of HRV vaccine. Similar malnourished conditions, such as in children in low and middle income countries, may contribute to microbiota changes and HRV vaccine failures. 9. Our studies have suggested that the best management practice would be to avoid initial contamination of the virus with ready-to-eat vegetables from farm to fork. Looking for economic reagents that can bind to the specific amino acid residues on the capsid proteins of HuNoV to prevent its contamination can be a future target. 10. Identification of novel approaches (e.g, probiotics and small molecules), an alternatives for antibiotics to control Campylobacter, have resulted in the reduction of Campylobacter in general and antimicrobial resistant in particular which will benefit the public health. This will benefit stakeholders by enhancing their capabilities to control this pathogen in their products, which would increase the competitiveness of chicken farming. 11. The Small molecule growth inhibitors identified in our studies will make available a novel and effective control method against Salmonella in poultry production system thus ensure food safety and public health 12. The whole genome analysis of the Salmonella isolated from poultry farms revealed contribution of horizontal gene transfer in Salmonella adaptations and antimicrobial resistance. These findings facilitate development of approaches to mitigate antimicrobial resistance. 13. The small molecules identified (growth as well as virulence inhibitors) in our studies will make available novel and effective control methods against colibacillosis in poultry production system and thereby enhance food security and food safety. H. N. Dakota 1. Methods to reduce time and labor involved in PEDV serological testing in diagnostic labs were developed. 2. USDA-NIFA funding was secured to test rapid-response PEDV vaccine which was very effective an safe in piglets, in a pregnant sow model. I. Tennessee 1. Development of innovative strategies to control Campylobacter infection in humans and in animal reservoir would reduce the occurrence of foodborne illness in humans. 2. Our antimicrobial resistance studies may open new avenues for treatment and prevention of resistant foodborne pathogens important in animal health and food safety. 3. Research on the development of alternatives to antibiotic growth promoters will lead to novel ‘One Health’ measures for enhanced animal production, food safety, and human health. 4. Development of IFN-based novel vaccine and antivirals for mitigating viral infections J. S. Dakota Our work using genmomic epidemiology helps to better understand the routes of transmission and mechanisms by which zoonotic pathogens such as Salmonellla enterica cause enteric infections. IN the longer term this could be helpful to design better food safety measures to control human infections.

Accomplishments

<p><strong>Objective 1. Focus on emerging diseases: We will identify, characterize and develop improved detection and prevention methods related to newly recognized, novel or emerging causes of zoonotic enteric disease and enteric pathogens of food animals.</strong></p><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Salmonella</em></strong></li><br /> </ol><br /> <p><strong>Kansas State University</strong></p><br /> <p>We determined how Salmonella restricts the entry of host transcription factors to the nucleus during infection.</p><br /> <p>&nbsp;</p><br /> <p>We solved the structures and defined the mechanisms of several Salmonella virulence factors.</p><br /> <p><strong>Washington State University</strong></p><br /> <p>&nbsp;</p><br /> <p>We have discovered and reported genomic organization and role of <em>Salmonella </em>pathogenicity island 13 in nutritional fitness of Salmonella</p><br /> <p>&nbsp;</p><br /> <p>We identified common highly expressed genes of Salmonella Enteritidis by in silico prediction of gene expression and in vitro transcriptomic analysis</p><br /> <p>&nbsp;</p><br /> <p>We reported that agricultural soils amended with biosolids in WA State were stable and contained enhanced soil source populations as well as bacteria likely found in biosolids. Pathogenic bacteria such as <em>Salmonella </em>were not detected.</p><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Shiga toxin-producing E. coli (STEC)and Enterotoxigenic E. coli </em></strong><strong>(ETEC)</strong></li><br /> </ol><br /> <p><strong>Kansas State University</strong></p><br /> <p>We quantified the prevalence of Shiga toxin-producing <em>E. coli </em>in swine feces using PCR and culture methods.</p><br /> <p>&nbsp;</p><br /> <p><strong>University of Nebraska-Lincoln</strong></p><br /> <p>The performance of three chromogenic agar media for the detection of USDA-FSIS adulterant-type Shiga toxin-producing <em>Escherichia coli</em> (STEC) in beef was compared.</p><br /> <p>Overall, modified Rainbow Agar&reg; O157 was more sensitive than modified Poss&eacute; Differential Medium, which was more sensitive than CHROMagar<sup>TM</sup> STEC in detecting STEC in ground beef samples.</p><br /> <p>&nbsp;</p><br /> <p><strong>The University of Tennessee</strong></p><br /> <p>Escherichia albertii is an emerging and the newest member of the A/E family of bacterial pathogens.&nbsp; E. albertii infection can cause characteristic attaching and effacing (A/E) lesions as observed in other A/E pathogens, such as enteropathogenic E. coli (EPEC) and enterohemorrhagic E. coli (EHEC). To date, the prevalence and major animal reservoirs of this pathogen are still largely unknown.&nbsp; With aid of our newly developed diagnosis method and selective medium, for the first time, we isolated E. albertii from the poultry production system and from a raccoon in the US, providing new insights into the epidemiology of E. albertii.</p><br /> <p>&nbsp;</p><br /> <p><strong>&nbsp;</strong></p><br /> <ol><br /> <li><strong><em>Campylobacter jejuni</em></strong></li><br /> </ol><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Brachyspira hampsonii and Lawsonii intracellularis</em></strong></li><br /> </ol><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Coronavirus</em></strong></li><br /> </ol><br /> <p><strong>Ohio State University</strong></p><br /> <p>New porcine epidemic diarrhea virus (PEDV) variants, with a large deletion in the N-terminal domain of the S1 subunit of spike (S) protein and designated as S1 NTD-del PEDVs, emerged in the field. They replicate in experimentally infected pigs. However, on farms they often co-infect pigs with the PEDV strains containing an intact S protein (S-intact PEDV). We characterized viral replication and pathogenesis in neonatal gnotobiotic pigs infected simultaneously with the two types of PEDV. We found that S-intact PEDV replicated to a higher peak titer when pigs were co-infected with S1 NTD-del PEDV.</p><br /> <p>&nbsp;</p><br /> <p>Porcine delta coronavirus (PDCoV) is an emerging enteric virus of pigs that causes severe diarrhea in neonatal pigs. We generated an infectious clone of PDCoV (icPDCoV) and experimentally infected neonatal gnotobiotic pigs with it. We confirmed that its virulence was similar to that of wild type PDCoV.</p><br /> <p>&nbsp;</p><br /> <p>We comparatively assessed the prevalence of &delta;- and &gamma;-CoVs in wild migratory terrestrial and aquatic birds in Arkansas, Illinois, Indiana, Maryland, Mississippi, Missouri, Ohio, Tennessee and Wisconsin in 2015-2018. We demonstrated that &delta;-CoV are less prevalent than &gamma;-CoVs and that both &delta;- and &gamma;-CoVs occurred more frequently in aquatic birds. For the first time, we identified HKU20-like &delta;-CoVs in the US.</p><br /> <p>&nbsp;</p><br /> <p>We evaluated if vitamin A (VA) supplementation of porcine epidemic diarrhea virus (PEDV)-infected pregnant gilts would enhance the gut-mammary gland-secretory IgA axis to boost lactogenic immunity and passive protection of nursing piglets against PEDV. Our results demonstrated that the VA-supplemented PEDV-infected gilts protected their piglets against PEDV challenge more efficiently than the non-VA supplemented gilts.</p><br /> <p>&nbsp;</p><br /> <p>&nbsp;</p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Calicivirus</em></strong></li><br /> </ol><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Rotavirus</em></strong></li><br /> </ol><br /> <p><strong>Ohio State University</strong></p><br /> <p>We comparatively assessed the pathogenesis of more recent (2012) and historic (1980) porcine rotavirus C strains in 3-day- and 3-week-old gnotobiotic piglets. We demonstrated that the current and historic RVC strains possess distinct pathobiological characteristics, with a newer strain-inducing more severe clinical disease and higher virus replication combined with decreased IgA antibody responses.</p><br /> <p>&nbsp;</p><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Immunological links underlying Viral obesity</em></strong></li><br /> </ol><br /> <p><strong>The University of Tennessee</strong></p><br /> <p>Obesity and its related comorbidities are prevailing globally. Multiple factors are etiological to cause obesity and relevant metabolic disorders. In this regard, some pathogenic infections including those by viruses have also been associated with obesity (termed especially as infectobesity). In this project, we have examined the primary or cofactorial role of viral infections to exacerbate the local and systemic immunometabolic cues that underlie most cofactorial obesity. Major immuno-metabolic pathways involved, including that mediated by interferon (IFN) signaling and peroxisome proliferator-activated receptor-&gamma; (PPAR-&gamma;), are focused on further studies.</p><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>Antimicrobial Resistance (AMR)</em></strong></li><br /> </ol><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>Washington State University</strong></p><br /> <p>We have completed a cross-sectional and ecological study on assessing the impact of antimicrobial use policy changes in pre-weaned dairy calves on antimicrobial resistance in commensal Escherichia coli</p><br /> <p>&nbsp;</p><br /> <p>We reported that dairy farm soil presents distinct microbiota and varied prevalence of antibiotic resistance across housing areas.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>The University of Tennessee</strong></p><br /> <p>The mobile colistin resistance has posed a significant threat to food safety. Our mechanistic and molecular epidemiology work demonstrated that 1) Transposition of <em>MCR-1</em> needs intact Tn6330 transposon, which includes its complete upstream (ISApl1, IRL) &amp; downstream (IRR,ISApl1) regions; and 2) Extensive heterogeneity and flexibility of <em>MCR-1</em> transmission exist in chicken gut from multiple aspects, including bacterial species difference, distant clonal relatedness of isolates, enormous types and variations of <em>MCR</em>-positive plasmids, and flexible genetic context of <em>MCR-1</em>.</p><br /> <p>&nbsp;</p><br /> <p><strong>University of Wyoming</strong></p><br /> <p>We evaluated a machine learning classifier in conjunction with similarity searches against identification libraries for the analysis of mass spectral fingerprints obtained by MALDI-TOF MS in order to improve microbial identification of select foodborne bacteria. MALDI-TOF MS coupled with library-based identification for all strains tested correctly identified 86% of the MALDI-TOF mass spectra at the species level. The machine learning neural net evaluated resulted in a significantly higher accuracy of discrimination of 95%.</p><br /> <p>&nbsp;</p><br /> <p>We developed a method to predict antimicrobial sensitive/resistant (S/R) phenotypes and host sources of Escherichia coli based on differential fatty acid abundance. Myristic, pentadecanoic acid, palmitic, elaidic and stearic acid were significantly different for predicting nalidixic acid, ciprofloxacin, aztreonam, cefotaxime, and ceftazidime S/R phenotypes. Linear regression models of fatty acid abundance made using a replicated-randomized subsampling and modeling approach predicted S/R phenotype with 79% and 81% accuracy for nalidixic acid and ciprofloxacin, respectively. The isolate host source was predicted with 63% accuracy.</p><br /> <p>&nbsp;</p><br /> <p><strong>Objective 2. Focus on preventions and interventions: We will develop and improve preventative measures and interventions to reduce the incidence and prevalence of infections of food animals with enteric and foodborne and waterborne pathogens.</strong></p><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Salmonella</em></strong></li><br /> </ol><br /> <p><strong><em>&nbsp;</em></strong></p><br /> <ol><br /> <li><strong><em>STEC and ETEC</em></strong></li><br /> </ol><br /> <p><strong>Kansas State University</strong></p><br /> <p>We characterized several small molecules that inhibit the activity of an essential E. coli virulence factor.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>University of Nebraska-Lincoln</strong></p><br /> <p>Two manuscripts were published in refereed journals (please see publication list, below).</p><br /> <p>&nbsp;</p><br /> <p>A fimbria-toxoid multiepitope fusion antigen vaccine for post-weaning enteric colibacillosis in swine was developed and tested for immunogenicity in mice by Dr. Weiping Zhang and graduate student Ti Lu and his laboratory.&nbsp; More information on the progress of this work will be provided in the Illinois station report.</p><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Campylobacter jejuni</em></strong></li><br /> </ol><br /> <p><strong>Iowa State University</strong></p><br /> <p>For the development of an experimental challenge model for <em>Campylobacter</em> abortion, timed bred, pregnant ewes at 40-45 days prior to lambing were challenged with <em>C. jejuni</em> clone SA via oral, intraperitoneal (IP), or intravenous (IV) routes. Ewes were monitored for up to 3-weeks for the evidence of abortion (vaginal bleeding, expelled fetuses); necropsy was performed as appropriate. Samples (uterus, placenta, fetal tissues) were collected for histopathology and culture for evaluation of parameters associated with fetoplacental infection with <em>Campylobacter</em>.</p><br /> <p>&nbsp;</p><br /> <p>Oral or IP inoculation failed to induce abortion in two trials despite the heavy inoculum size and was thus discontinued. However, IV inoculation induced specific abortion reliably after several trials in which different combinations of factors (inoculum dose, free endotoxin level in the inoculum, and premedication of ewes with an anti-inflammatory drug) were adjusted. In all specific abortions, <em>Campylobacter</em> was isolated heavily from uterus, placenta and fetal tissues, as well as uterine and placental inflammation with typical microscopic lesions of Campylobacter infection, were evident.</p><br /> <p>&nbsp;</p><br /> <p>We performed immunization and challenge studies to evaluate vaccine-induced immunity against clone SA-associated sheep abortion. Two commercial <em>Campylobacter</em> vaccines and an experimental bacterin (made of a clone SA strain) were administrated subcutaneously into pregnant ewes twice. Two weeks after the second dose, the animals were challenged by intravenous inoculation with clone SA strain.</p><br /> <p>&nbsp;</p><br /> <p>Both commercial vaccines and the experimental bacterin induced high antibody titers against <em>C. jejuni</em> clone SA, but immunoblotting results showed that the experimental bacterin induced more specific antibodies to clone SA. Notably the experimental bacterin produced 80% protection compared with the sham-vaccinated controls, whereas the commercial vaccines did not significantly differ from the sham controls in abortion rates.</p><br /> <p>&nbsp;</p><br /> <p>To evaluate the efficacy of tulathromycin to prevent abortion, pregnant ewes were challenged IV with clone SA and given s.c. tulathromycin 18 hr post-challenge. When compared to the sham-treated controls, tulathromycin treatment resulted in a significant decrease in the rate of vaginal bleeding/abortion in animals.</p><br /> <p>&nbsp;</p><br /> <p>To understand how <em>C. jejuni</em> interacts with the host placenta and how the interaction results in abortion remain, we profiled the host-pathogen responses in sheep placenta with <em>C. jejuni</em> clone SA infection by high-throughput sequencing of both host and bacterial RNA (dual RNA-seq). Gene enrichment analysis showed that the up-regulated genes in the infected placenta were primarily enriched in the pathways of immune responses, while the up-regulated genes in <em>C. jejuni</em> IA3902 were enriched in the pathways of metabolisms.</p><br /> <p><strong>Ohio State University</strong></p><br /> <p>We identified two novel narrow-spectrum Campylobacter specific small molecule growth inhibitors having MIC of less than 50 &mu;M with restricted effects on other prokaryotes. The compounds reduced C. jejuni burden in broiler chicken&rsquo;s ceca when treated for 5 days with 100 ug/chicken and had minimal impact on the cecal microbiota.&nbsp;</p><br /> <p>&nbsp;</p><br /> <p>We assessed the prevalence and abundance of Campylobacter spp. in young children's stools (n=100) from eastern Ethiopia and its association with the stool microbiome, environmental enteric dysfunction (EED) and diarrhea status of the children. High prevalence in Campylobacter (88%) and high species diversity (n=39) were detected in the children's stools collected from Ethiopia. Further, we observed that the Campylobacter prevalence, EED severity, and diarrhea status had an impact on the stool microbiome profile.</p><br /> <p>&nbsp;</p><br /> <p>We evaluated the Campylobacter colonization in chickens vaccinated with six Recombinant Attenuated Salmonella Vaccines (RASVs). The chickens were challenged with a cocktail of 5 chicken origin C. jejuni strains. Preliminary studies showed promising results with some vaccines with the reduction in cecal Campylobacter load.</p><br /> <p>&nbsp;</p><br /> <p><strong>The University of Tennessee</strong></p><br /> <p>We continued to develop and assess enterobactin (Ent) antibody-based immune intervention strategies. The anti-Ent antibodies displayed potent inhibitory effects on a panel of diverse Gram-negative pathogens, including <em>E. coli</em>, <em>Salmonella</em>, and <em>Campylobacter</em>. Multiple vaccination trials have been performed to assess the efficacy of the KLH-Ent conjugate vaccine and to prepare Ent-specific egg yolk antibodies.</p><br /> <p>&nbsp;</p><br /> <p><strong>University of Arkansas</strong></p><br /> <p>We have found that secondary bile acid deoxycholic acid and its modulated anaerobic microbiota prevent C. jejuni chicken colonization.</p><br /> <p>&nbsp;</p><br /> <p>We have found that deoxycholic acid-modulated anaerobes reduce chicken transmission-exacerbated intestinal inflammation in Il10-/- mice.</p><br /> <p>&nbsp;</p><br /> <p>We have identified that mouse-specific pathogen-free (SPF) anaerobes prevent C. jejuni chicken colonization.</p><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Brachyspira hampsonii and Lawsonii intracellularis</em></strong></li><br /> </ol><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Coronavirus</em></strong></li><br /> </ol><br /> <p><strong>Kansas State University</strong></p><br /> <p>We reported the mechanism of virus entry of porcine epidemic diarrhea virus (PEDV) genogroup 2 US strains.</p><br /> <p>&nbsp;</p><br /> <p><strong>Ohio State University</strong></p><br /> <p>We generated a live attenuated PEDV vaccine candidate by inactivating the 2&rsquo;-O methyltransferase (2&rsquo;-O MTase) activity of nsp16 and the endocytosis signal of the spike protein using reverse genetics technology.&nbsp;</p><br /> <p>&nbsp;</p><br /> <ol><br /> <li><strong><em>Calicivirus</em></strong></li><br /> </ol><br /> <p><strong>Ohio State University</strong></p><br /> <p>Lettuce is often implicated in human norovirus (HuNoV) foodborne outbreaks.

We demonstrated that the replication of virulent but not attenuated RVA strains in PIEs was significantly affected by the HBGA type.</p><br /> <p>&nbsp;</p><br /> <p>We studied the effect of tryptophan (Tryp) and the probiotic <em>Escherichia coli </em>Nissle 1917 (EcN) as dietary supplements on the gut microbiota of HIFM transplanted Gn pigs fed with deficient diet (malnourished) and challenged with HRV. Both Tryp and EcN treatments reduced diarrhea severity and viral shedding and improved the body weight gain and gut microbiota composition of treated pigs compared to not treated group. Both treatments increased the abundance of beneficial bacteria (i.e. <em>Enterococcus, Bifidobacterium</em>, and <em>Bacteroides</em>) and decreased the abundance of inflammation-associated bacteria (i.e. <em>Halomonas</em> and <em>Shewanella</em>).</p><br /> <p><strong>&nbsp;</strong></p><br /> <ol><br /> <li><strong><em>Avian pathogenic E. coli (APEC)</em></strong></li><br /> </ol><br /> <p><strong>Ohio State University</strong></p><br /> <p>We identified three novel SM growth inhibitors (GI) with potent anti-APEC efficacy in chickens.
