Emerging Infections Program Survey for Antimicrobial-Resistant Enterococci Among Outpatients and Food Samples
The goal of this study is to determine the prevalence of clinically important, antimicrobial-resistant enterococci among persons outside the healthcare setting and on the surface of poultry or other meat products sold for human consumption. This study began in June 1998 with 3 participating sites: Oregon, Georgia, and Maryland. Since that time, the study has expanded by 2 sites: Minnesota Health Department and William Beaumont University in Michigan.
State Laboratory Participation
Human stool isolates are obtained from outpatients or healthy volunteers. State laboratories also purchase food at retail each month. From July 1998 to June 1999 poultry was tested, from July 1999 to June 2000 ground pork was tested. Enterococci isolated from human stool and food are screened for three clinically relevant forms of antimicrobial resistance in enterococci: high-level vancomycin resistance, high-level gentamicin resistance, and quinpristin-dalfopristin (Synercid) resistance. The predominant enterococci will be isolated and saved regardless of the presence of antimicrobial resistance. All Enterococcus isolates are forwarded to CDC for further testing.
