Hooves, Paws, or Feet: A Multispecies Examination of Antimicrobial Use and Stewardship Practices

Have you ever thought about antimicrobial resistance (AMR) as a major health challenge in animals? Antimicrobial-resistant germs can infect not only humans, but domesticated pets and livestock, too. To better understand factors influencing AMR in animals, CDC is leading a discussion with animal experts on how to address AMR through antibiotic stewardship, understanding veterinary prescribing practices, and biosecurity and infection prevention measures that can be implemented to ensure health of animals and people. Join us to hear more from these experts working to learn more about AMR in animals, understand its impact on public health, and take action to address the spread of AMR.


Megin Nichols
Activity Lead, Enteric Zoonoses
U.S. Centers for Disease Control and Prevention
Megin Nichols, DVM, MPH, DACVPM, is an Enteric Zoonoses Activity Lead at the Centers for Disease Control and Prevention. She was an Epidemiologic Intelligence Service Officer from 2008–2010 with the New Mexico Department of Health. Prior to obtaining her DVM, she spent several years as a clinical veterinary assistant. Dr. Nichols has focused her work on investigating multistate outbreaks of human illness linked to petting zoos, small turtles, livestock with strains of multidrug-resistant Salmonella, and pet food products. Dr. Nichols received a B.S. in Animal Science from New Mexico State University, a Doctor of Veterinary Medicine from Colorado State University, and a Master of Public Health in Food Safety and Biosecurity from the University of Minnesota.


Greg Habing
Veterinary Epidemiologist
Ohio State University
Greg Habing, DVM, MS, PhD, is a veterinary epidemiologist at The Ohio State University's College of Veterinary Medicine. Dr. Habing leads the food safety course within the Veterinary Public Health specialization for MPH students and teaches within epidemiology, zoonoses, and preventive medicine courses. His research team at OSU, The One Herd Lab, combines production system experience with expertise in traditional and molecular epidemiology to address critical One Health problems, including antimicrobial stewardship and the foodborne transmission of pathogens. This team is designing and assessing the impact of educational and behavioral interventions on antimicrobial use behaviors and antimicrobial resistance in dairy and calf production systems. Additionally, it is working to identify pre-harvest interventions to interrupt the transmission of multidrug resistant Salmonella species, from livestock markets and calf production systems.
Paul Plummer
Executive Director
National Institute of Antimicrobial Resistance Research and Education
Professor and Chair in Veterinary Science
Iowa State University
Paul Plummer, DVM, PhD, DACVIM, DECSRHM, is the executive director of the National Institute of Antimicrobial Resistance Research and Education (NIAMRRE), housed at the Iowa State University Research Park. Dr. Plummer is also a professor and chair in Veterinary Science at the ISU College of Veterinary Medicine. NIAMRRE’s mission is to drive collaborative and integrative research, education, and engagement to solve AMR challenges and benefit society using a One Health approach. NIAMRRE also provides local, national, and international leadership in combating antimicrobial resistance; generating evidence-based solutions for antimicrobial stewardship; contributing to improvements in the health of animals, humans, and the environment; and facilitating economically and socially sound policy development and implementation.
Dan Taylor
Veterinary Epidemiologist
EpiX Analytics
Dan Taylor, DVM, PhD, DACVPM, is a veterinary epidemiologist for EpiX Analytics in Fort Collins, Colorado. Dr. Taylor received his DVM from Iowa State University and recently completed his PhD in epidemiology from the Colorado School of Public Health. He combined his small animal practice experience and interest in antibiotic use and resistance in his dissertation, "Antimicrobial drug use and resistance in companion animal medicine." His research explored how veterinarians prescribe antibiotics, how pet owners perceive antibiotic use in pets, and how veterinary antibiotic prescribing practices compare to human medicine.
