Antimicrobial Susceptibility Monitoring Report Available

December 1, 1998

This CVM Update was edited April 24, 2009, to remove the link to the outdated report entitled "National Antimicrobial Susceptibility Monitoring Program -- Veterinary Isolates."

The Food and Drug Administration (FDA), U.S. Department of Agriculture (USDA), and Centers for Disease Control and Prevention (CDC) report entitled "National Antimicrobial Susceptibility Monitoring Program -- Veterinary Isolates, April, 1998" is now available from CVM's Internet Home Page. The report is located here. Copies are also available by calling or writing CVM's Communications Staff at FDA/Center for Veterinary Medicine, HFV-12, 7500 Standish Place, Rockville, MD 20855, 301-594-1755.

The emergence of resistance to antimicrobials has compromised control of many bacterial pathogens and is a global problem. Additionally, multiple drug resistance has emerged among many bacterial strains, including Salmonella species. The development of resistant pathogenic bacteria occurs from the human, animal, and environmental uses of antimicrobials. Food animals are commonly exposed to antimicrobials for therapeutic indications and to improve feed efficiency and weight gain. The intestinal flora of animals that have been exposed to antimicrobial agents can serve as a reservoir of resistant bacteria, and these organisms may be present on animal derived food products.

FDA, USDA, and CDC established the National Antimicrobial Resistance Monitoring System (NARMS) in January 1996 to monitor changes in antimicrobial susceptibilities of zoonotic pathogens from human and animal clinical specimens, from healthy farm animals, and from carcasses of food-producing animals at slaughter.

This report summarizes the percentage of isolates collected during calendar year 1997 that were susceptible, intermediate, or resistant to 17 antimicrobials. These antimicrobials were chosen to be representative of common antimicrobials (or classes of antimicrobials) used in animal and human medicine.
