ABSTRACT
Prevalence and antimicrobial susceptibility of Enterococcus spp. were evaluated in 360 frozen unse asoned chicken carcasses samples collected from September 2004 to June 2006 from the retail stores in São Paulo State, Brazil. Enterococcus spp. was isolated from all analyzed samples, and 1,332 strains were identified from them. Among the ten identified species, the predominance of E. faecalis, E. gallinarum, E.casseliflavus and E. faecium was occurred. All of the Enterococci strains showed some degree of resistanceto the nine antimicrobials utilized in the study. The percentages of antimicrobial resistance were 89.2% for tetracycline, 91.4% for quinupristin-dalfopristin, 83.5% for erythromycin, 65% for ciprofloxacin, 55.4% for chloramphenicol, 6.5% for linezolid, 2.3% for vancomycin, 2.3% for teicoplanin and 0.2% for ampicillin. The occurrence of the high level resistance to amyno glicosides (HLR-A) was detected in 57.4% of the isolates. E. faecalis and E. faecium species, which are considered as important agents in nosocomial infections, showed resistance to eight and seven antibiotics, respectively.
