Antibacterial Resistance of Commensal E-coli and E-coli O157:H7 Strains Isolated from Cattle and Calves Faeces Samples

This study investigated the occurrence and antimicrobial resistance profiles of E. coli and E. coli O157:H7 isolated from cattle and calves faeces samples in Afyonkarahisar. A total of 45. coli and 14 E. coli O157:H7 species was isolated. All the E. coli isolates were found to be resistant to the penicillin. However, E. coli O157:H7 species were found to be resistant to the penicillin, ertiyromisin and neomycin. Most of E. coli isolates were found to be resistant to the eritromisin (97.7%), neomycin (95.6%), tetracyclin (73.3%) and ampicillin (60.0%). The tetracyclin to the considerably resistance were seen in both pathogens although, arnpicillin resistance was relatively higher in E. coli than in E. coli O157:H7 species. This study observed that cephalothin and cefoxitun. resistances were found to highly different the E. coli and E. coli O157:H7 strains. In addition the lowest frequency of resistance was seen against both cefoxitim and ciprofloxacin (7.2%).
