dc.description.abstractFood-producing animals can harbor Escherichia coli strains with potential to cause diseases in humans. In this study, the presence of enteropathogenic E. coli (EPEC) was investigated in fecal samples from 130 healthy sheep (92 lambs and 38 adults) raised for meat in southern Brazil. EPEC was detected in 19.2% of the sheep examined, but only lambs were found to be positive. A total of 25 isolates was characterized and designated atypical EPEC (aEPEC) as tested negative for bfpA gene and BFP production. The presence of virulence markers linked to human disease as ehxA, paa, and IpfAO(113) was observed in 60%, 24%, and 88% of the isolates, respectively. Of the 11 serotypes identified, eight were described among human pathogenic strains, while three (O1:H8, O11:H21 and O125:H19) were not previously detected in aEPEC. Associations between intimin subtypes and phylogroups were observed, including eae-theta 2/A, eae-beta 1/B1, eae-alpha 2/B2 and eae-gamma 1/D. Although PFGE typing of 16 aEPEC isolates resulted in 14 unique pulsetypes suggesting a genetic diversity, specific clones were found to be distributed in some flocks. In conclusion, potentially pathogenic aEPEC strains are present in sheep raised for meat, particularly in lambs, which can better contribute to dissemination of these bacteria than adult animals.
