| ABSTRACT The aim of this study was to investigate the presence of shiga toxin-producing Escherichia coli (STEC) and atypical enteropathogenic Escherichia coli (aEPEC) in frozen chicken carcasses sold at stores in southern Brazil. Typical E. coli colonies were enumerated in 246 chicken carcasses, and the presence of stx1, stx2, eae genes was investigated in their rinse liquid and in E. coli strains isolated from those carcasses. Strains of E. coli were also investigated for the presence of bfp gene. A median of 0.6 cfu.g-1(ranging from <0.1 to 242.7 cfu.g-1) of typical E. coli colonies was found in the carcasses. Shiga toxin-encoding genes (stx1 and stx2) were not detected, indicating that the chicken carcasses were negative for STEC. The intimin protein... |
