National Antimicrobial Resistance Monitoring System


Dr. Patrick McDermott is Director of the Division of Animal and Food Microbiology and Director of the National Antimicrobial Resistance Monitoring System (NARMS) at the Office of Research. NARMS was established in 1996 and is an interagency collaborative effort between the FDA, USDA and CDC that tracks antibiotic resistance in bacteria from retail meats, food producing animals and human clinical cases of infection. DAFM conducts the retail meat testing component of NARMS, and conducts microbiological research related to animal health and food safety.  His work is aimed at understanding the genetic mechanisms of antibiotic resistance, how resistance emerges and spreads, and the impact of interventions designed to limit resistance in food animal production.


  • The evolution, persistence and spread of antimicrobial resistance in foodborne bacteria
  • Molecular epidemiology of antimicrobial resistance genes
