The aim of this study was to isolate and analyze the antimicrobial profile resistance of Enterococcus from cooled and frozen poultry carcasses commercialized at the Federal District area, detecting the antimicrobial resistance genes and identifying Enterococcus faecalis and Enterococcus faecium by polymerase chain reaction. One hundred poultry carcasses were analyzed and 50 strains of Enterococcus spp. were isolated, of which 42% were E. faecalis and 2% E. faecium. The antimicrobial susceptibility test showed that all isolates were resistant to at least one antibiotic; 90,47% of E. faecalis, 100% of E. faecium and 82,14% of Enterococcus spp. were resistant to Tetracycline; 80,95% of E. faecalis and 35,71% of Enterococcus spp. strains were resistant to Erythromycin; 39,28% of Enterococcus spp. and 23,80% of E. faecalis to Ciprofloxacin, and 28,57% of E. faecalis were resistant to Chloramphenicol. There were detected erm(B), vanC-1, aph(3')-llla, ant(6)-la, vanB, vanA, aac(6')-le-aph(2 '')-la, erm(A) and tet(M) resistance genes, the last one most often verified. The results might suggest problems for public health due the high resistance, since these microorganisms have ability to transmit genes for antimicrobial resistance to others in the intestinal tract of humans and animals. Thus, the use of these drugs for clinical treatment could be hindered.
