215: One Health, Many Species: AMR Through a Veterinary Lens

What does antimicrobial resistance look like when your patients range from dogs and cats to cattle, wildlife, and everything in between? And how do we make sense of AST, breakpoints, contamination, and genotypic tools across such a diverse microbiological world? In this episode, Luis is joined by Dr. Kelli Maddock, DrPH (North Dakota State University Veterinary Diagnostic Laboratory) and Dr. Stephen Cole (University of Pennsylvania), two leaders shaping the future of veterinary microbiology, antimicrobial stewardship, and CLSI veterinary standards. Together, they explore AMR and AST through a true One Health lens, showing how animal, human, and environmental health are interconnected in everyday diagnostic work. Drawing from their recent American Journal of Veterinary Research article on AMR challenges in veterinary medicine, the discussion highlights: The biggest challenges in veterinary AST, from species diversity to contamination Phenotypic vs genotypic testing and concerns around WGS-based "treatment predictions" How selective reporting ("nudging") strengthens antimicrobial stewardship Why every animal result matters in a One Health framework Whether you come from human or veterinary microbiology, this episode reveals the shared challenges across sectors — and the diagnostic, collaborative, and educational steps needed to strengthen AMR response in a One Health world.
