dc.description.abstractDuring processing of cattle carcasses, contamination may occurs with the transfer of microbiota of animals feaces to carcasses. This contamination many times may be by Escherichia coli carriers of virulence factor as stx and eae genes being classified as Shiga like toxin. Shiga toxin-producing Escherichia coli (STEC) is recognized wordwide as human pathogen. A survey was performed to determine the sensibility profile to several antimicrobial drugs of STEC in carcasses obtained from an abattoir in Brazil between March 2008 and August at 2009. A total of 120 STEC were isolated. All isolates were confirmed as being E. coli by their biochemical analysis and submitted to polymerase chain reaction (PCR) for detection of stx, eae and ehly genes. No strains was isolated being carriers of ehly gene. The number of isolates carriers of eae gene were 48/120. The most frequent resistance was seen against cephalothin (84.0%), streptomycin (45.0%), nalidixic acid (42.0%) and tetracycline (20.0%). Multidrug resistance (MDR) to three or more antimicrobial agents was observed in 46 (38.3%) E. coli isolates. The findings of STEC and MRD show that cattle carcasses may be a reservoir of pathogenic bacterial for the consumer public. © 2011 Academic Journals.en
