NARMS Now

Welcome to NARMS Now: Human Data, an interactive tool from CDC that contains antibiotic resistance data from bacteria isolated from humans as part of the National Antimicrobial Resistance Monitoring System (NARMS). NARMS Now: Human Data makes it easier and quicker to find out how antibiotic resistance has changed over the past 20 years for four bacteria transmitted commonly through food—Campylobacter, E. coli O157, Salmonella, and Shigella.
