Impact Statements

Antimicrobial resistance is a major concern from the One Health perspective, which must be addressed using a multidisciplinary and collaborative approach across the animal, human and environmental health spheres. The NC 1206 Multi-State Research Project has collaborated to accomplish key studies and extension education activities that advance the knowledge, outreach, interdisciplinary collaboration, and mitigation efforts related to antimicrobial resistance. Social sciences have been integrated into education programs to target potential antimicrobial user biases, increase AMR knowledge, and to reach stakeholders across the food chain; the addition of social sciences strengthens the approach and allows for more targeted education of stakeholders. Several mitigation and resistance mechanism collaborations have developed as a result of this collaboration.

Brief Summary of Minutes

Brief Summary of Minutes of Annual Meeting:

The meeting started with a brief welcome and introduction of all members. The meeting was moderated by Kelli Maddock and Dr. Emmanuel Okello. Dr. George Smith provided a recorded welcome to NC1206 members.

Dr. George Smith, scientific advisor for the NC1206 project, provided recorded remarks to the group The project was renewed and updated on 10-1-22. There are 24 registered participants in the projects. He encouraged the group to consider putting in an application for the Excellence in Multistate Research Project Award. The impact summary would be a good basis for the application. Need tangible impacts, such as tools and resources that impact industry. Projects grounded in collaboration across multiple stations are imperative. Dr. Smith is willing to assist with application preparation. As a group, members later reviewed the requirements for the 2023 Experiment Station Section Award for Excellence in Multistate Research. Requirements will be shared with the group for review and to determine if we would like to apply.

Research Updates: Drs. Cazer, Ganda, Okello, Ivanek, Plummer, Gill, Schmidt, Wang, Li, and Kelli Maddock presented current research and future collaboration interests.

Guest speakers: Dr. Amy Schmidt, iAMResponsible Project, highlighted resources developed by the iAMResponsible team that are publicly available for use, including social media products, podcasts, and real-life experiences from individuals who have experienced an antimicrobial resistant infection. Dr. Schmidt’s team can develop social media resources for researchers. The group is available as the education/extension component on grants as subcontractors.

Dr. Kathe Bjork, USDA NIFA, provided updates regarding personnel updates at NIFA as well as budgetary notes. Several competitive funding opportunities were included in the update along with program contacts for each program. This update will be provided to meeting members.

New leadership: Kelli Maddock formally transitioned to the role as president of NC1206. Thank you to Dr. Okello for serving as president. Dr. Casey Cazer was unanimously elected as the group secretary.

Annual meeting schedule, 2024: The short time between the 2022 and 2023 meetings limited travel funding for some members as funding was dependent upon fiscal year. Three meeting options were discussed. The final dates and locations will be determined through discussion of members in late 2023.

Cornell- AMR Symposium to be held in Ithaca. March 2024. Could potentially host our group.

NDSU VDL in Fargo is willing to host. Food could be catered by the university and delivered to the laboratory. Would include a tour of the facility. Fargo has a vibrant restaurant scene and is pleasant to visit during the months of May- September.

NIAMRRE: 2024 Meeting scheduled for Ohio. Dr. Paul Plummer offered another joint meeting opportunity if we would like to coordinate the meeting times again.

Accomplishments

Accomplishments: Objective 1: Develop knowledge and tools to improve antimicrobial stewardship, including surveillance and monitoring of antimicrobial resistance, determining the ecology and mechanisms involved in resistance and transmission of resistance, and developing improved diagnostic tests <ol> <li>Integrating online platform to comprehensively assess antibiotic resistance gene pool (AR resistome) by shotgun sequencing analysis [OH] <ol> <li>Activities: assessed total and specified AR gene pools in fermented foods, human and animal gut microbiome.</li> <li>Outputs: Revealed that conventional oral administration of mainstream antibiotics such as ampicillin, vancomycin, clindamycin etc. led to broad disruption of gut microbiota in human and animal hosts, and the changes of antibiotic resistome. Revealed fermented food consumption led to the surge of gut (fecal) antibiotic resistome in most consumers, but the control high plant fiber food consumption didn’t have this effect. Revealed the prevalence of antibiotic resistome in traditionally fermented foods. The method enabled comprehensive assessment of the AR risk.</li> </ol> </li> <li>Antibiotic resistance in fermented foods and the impact on host gut resistome [OH] <ol> <li>Activities: Using culture dependent and independent methods revealed that traditionally fermented foods such as kimchi and artisan cheeses are highly prevalent in antibiotic resistant bacteria and opportunistic pathogens (~90% in retail kimchi and all 4 artisan cheeses assessment) and resistome.</li> <li>Outputs: Supported the finding that fermented foods consumption led to the surge of antibiotic resistome in gut microbiota of consumers. The results revealed a critical avenue of AR transmission and the underestimated food safety and public health risk associated with traditional food fermentation. The results presented a public health warning regarding the aggressive advocacy in recent years promoting fermented food consumption, especially towards targeted susceptible populations with compromised gut and immune functions. The results demand for prompt responses from the federal agencies and industry, in collaboration with academic experts to develop effective and targeted mitigation of antibiotic resistance in food fermentation.</li> </ol> </li> <li>Development of a Matrix-Assisted Laser Desorption Ionization Time-of-Flight (MALDI-TOF) assay to discriminate pathogenic from commensal strains of Histophilus somni: A novel and affordable diagnostic tool for bovine respiratory disease in North Dakota cattle herds.

Impact Statements

According to the World Health Organization and the Centers for Disease Control and Prevention, antimicrobial resistance is one of the greatest threats to the health of humans, animals, and the environment. When considering health across humans, animals, and plants, the approach should be viewed from a “One Health” perspective, which must be addressed using a multidisciplinary and collaborative approach. Members of the NC 1206 Multi-State Research Project have collaborated to accomplish key studies and extension education activities that advance the knowledge, outreach, interdisciplinary collaboration, and mitigation efforts related to antimicrobial resistance. Social sciences have been integrated into education programs to target potential antimicrobial user biases, increase AMR knowledge, and to reach stakeholders across the food chain. The addition of social sciences strengthens the approach and allows for more targeted education of stakeholders.

Brief Summary of Minutes

Accomplishments

Objective 1: Develop knowledge and tools to improve antimicrobial stewardship, including surveillance and monitoring of antimicrobial resistance, determining the ecology and mechanisms involved in resistance and transmission of resistance, and developing improved diagnostic tests <ul> <li>Enhancing performance of antimicrobial susceptibility testing (AST) in support of Vet-LIRN activities. Food and Drug Administration (FDA). Methods comparison of Sensititre Broth Microdilution to Vitek 2 Compact for AST of Enterobacterales, Pseudomonas aeruginosa, Staphylococcus pseudintermedius, and Enterococcus Evaluation suggestions consistent under calling of resistance for certain antimicrobials by Sensititre methods. Publication in progress [ND PA]</li> <li>Follow-up survey of AAVLD laboratory participants in the 2023 IBQAS AST exercise. [ND PA MA]</li> <li>Building AMR monitoring capacity through expanding NGS capabilities. Interdisciplinary sharing of Enterococcus and Pseudomonas aeruginosa isolates for NGS to AST comparison. Furthers the understanding of genotypic and phenotypic correlation of antimicrobial resistance. [MS PA NC ND MS WA MI]</li> <li>Comparison of Etest to Sensititre broth microdilution for antimicrobial susceptibility testing of Streptococci evaluated by the NAHLN AMR monitoring program. [ND CA WA MS]</li> <li>Expanded MICs for Veterinary pathogens to assist in ECOFF development. In progress [NE IA]</li> <li>Development of disc diffusion MIC correlation data for veterinary pathogens. In progress [NE KS]</li> </ul> Objective 2: Develop and Evaluate Antimicrobial Use Resistance Transmission Mitigation Strategies <ul> <li>Dietary interventions to enhance intestinal health of nursery pigs without or to reduce the use of antimicrobial growth promoters in feeds. Interventions include: bacterial cell wall compounds, yeast cell wall compounds enhancing mucosal immunity without antibiotics, feed enzymes to hydrolyze antinutritional soluble non-starch polysaccharides, phytase to hydrolyze antinutritional phytate in feeds, antioxidative phytogenic polyphenolic compounds, reduced protein diets to limit the growth of ammonia producing bacteria in the small intestine. [NC, GA, WI, MN]</li> <li>Establishing a ranking system for ARGs based on their human health impact, which is designed to be integrated with surveillance data collected from two agricultural watersheds in Nebraska and Iowa to estimate the associated human health risks. The severity of human health outcomes resulting from exposure to ARGs was evaluated based on four criteria: the human accessibility potential index, mobility, relation to pathogenicity, and the importance of the antibiotics to which the genes confer resistance. Using this developed framework, over 400 genes can be ranked. The innovative approach represents an advancement in next-generation risk assessment by incorporating genomic data, which may facilitate more effective surveillance of quantifiable health risks, resonating with the "One Health" initiative. [NE, IA, NY]</li> <li>One Health Analysis of Salmonella enterica Serotype Newport Isolated from Humans and Exotic Felids. Established interdisciplinary communication between state veterinary CDC and FDA regarding on-going Salmonella detection from exotic animal species in zoos. Development of public health centric messaging to diverse stakeholders. Increases visibility of foodborne pathogens circulating in veterinary medicine and their potential connections to human outbreaks. [ND MN FDA CDC]</li> <li>Determine phylogenetic relationships, antimicrobial resistance determinants, and virulence potential of Dublin from cattle and humans in the United States. Salmonella Dublin is highly multidrug resistant and virulent. It has been increasingly isolated from human bloodstream infections. Better understanding the genomic epidemiology of this pathogen might aid in better prevention strategies. [PA, ND, NE]</li> </ul> Objective 3: Create and Deliver Programs on Antibiotic Stewardship <ul> <li>AVMA Document on resistant bovine pathogens. On working group for updating list in collaboration with American Association of Bovine Practitioners. In progress. [NE, KS]</li> </ul> Funding  “CAMRADES connecting antimicrobial resistance, agricultural decisions, and environmental systems: A tool for mitigating AMR and assessing risk to human health in agro-ecosystems”. 2022-2026.
