National Antimicrobial Resistance Monitoring System for Enteric Bacteria


The National Antimicrobial Resistance System for Enteric Bacteria (NARMS) program monitors changes in antimicrobial drug susceptibilities of selected enteric bacterial organisms in humans, animals, and retail meats to a panel of antimicrobial drugs important in human and animal medicine. The primary objectives of NARMS are (1) to provide descriptive data on the extent and temporal trends of antimicrobial drug susceptibility in Salmonella and other enteric bacterial organisms from human and animal populations, as well as in retail meats; (2) to facilitate the identification of antimicrobial drug resistance in humans, animals, and retail meats as it arises; and (3) to provide timely information to veterinarians and physicians on antimicrobial drug resistant patterns.

Selected Content: 
Population Covered: 
Bacterial isolates are collected from human and animal clinical specimens, from healthy farm animals, from raw product from food animals, and from retail meats collected from grocery stores. In 2008, surveillance was conducted in all 50 states for non-typhoidal Salmonella, typhoidal Salmonella, Shigella, and Escherichia coli O157. For Campylobacter, surveillance was conducted in 10 states that comprise the Foodborne Diseases Active Surveillance Network (FoodNet), representing approximately 46 million persons (15.2% of the U.S. population).
