Escherichia coli antibioresistance in broiler chicken with collibacillosis.

摘要

Two-hundred-and-fifty-one E. coli isolates were recovered from broilers with clinical signs and lesions of colibacillosis in the West area of Algeria. Serotyping showed that 82% of the isolates belong to one of the serotypes O78, O2 and O1. Antibiograms revealed a high level of resistance to oxytetracycline, amoxicillin, ampicillin and trimethoprim-sulfmethoxazole. However, only a low percentage of strains was resistant to enrofloxacin but multiple drug resistance was common..
