Enteric Diseases Laboratory Branch

National Antimicrobial Resistance Surveillance Team (NARST)

The National Antimicrobial Resistance Surveillance Team conducts antimicrobial resistance surveillance and applied research among foodborne enteric bacteria (pathogens and commensal organisms). Susceptibility testing and other analyses are performed on bacterial isolates from foodborne disease outbreaks, focus studies, and human isolate submissions to the National Antimicrobial Resistance Monitoring System (NARMS). NARMS is a collaboration between the Centers for Disease Control and Prevention (CDC), the Food and Drug Administration Center for Veterinary Medicine (FDA-CVM), and the United States Department of Agricultural Research Service (USDA-ARS). NARMS human isolate monitoring is conducted in partnership with the Enteric Diseases Epidemiology Surveillance Branch; FDA-CVM and USDA-ARS conduct studies on bacteria isolated from retail meats and food animals, respectively.
