Abstract:
The present study was undertaken to determine the occurrence of E. coli in different livestock species and poultry in Patna, Bihar. A total of 254 samples comprising of cow milk, buffalo milk, poultry cloacal swab and goat rectal swab were processed for isolation of E. coli. Based on PCR 34.7% of cow milk samples, 48.4% of buffalo milk samples, 77.6% of goat rectal swab samples and 78.4% of poultry cloacal swab samples were found positive for E. coli which were tested for phenotypic resistance against colistin by MIC testing. 12% (3/25) cow milk isolate, 32.2% (10/31) buffalo milk isolate, 5.7% (3/52) isolate from goat rectal swab and 15% (6/40) isolates from poultry were phenotypically found resistant to colistin based on MIC value which need further genotypic confirmation.
