Antimicrobial resistance can be seen in almost all pathogenic bacteria present in food like chicken meat, leading to treatment failure in human patients and serious public health problems. The present study aimed to detect extended-spectrum beta-lactamases (ESBLs) and AmpC beta-lactamase (ACBL)-producing Escherichia coli from chicken meat, from different parts of West Bengal. A total of 113 raw chicken meat samples were collected during slaughter from different local markets followed by isolation and identification by standard conventional and molecular methods. About79% samples were positive for E. coli and among 89 isolates 17(19.1%) were positive to ESBL property and presence of the blaCTX-M gene, whereas 78 strains (87.6%) were found to possess blaAmpC gene. Antibiogram study of ESBL positive E. coli strains revealed resistance of these strains to ceftriaxone, ampicillin (both 100%), amoxicillin/clavulanic acid, ceftazidime, cefotaxime, tetracycline (all approx. 94%), azithromycin (70.6%) and norfloxacin (64.7%) in-vitro whereas imipenem (94%), amikacin (82%), gentamicin (58.8%) and ampicillin/sulbactam (71%) were quite effective against these MDR isolates. So, about 79% of chicken meat samples were found to be contaminated with E. coli, most of which were resistant to commonly used antibiotics which may lead to animal and human health hazards.
