Antibiotic resistance profile of Escherichia coli isolated from pork and chicken meat selling in retain markets in Gia Lam district, Ha Noi City

Abstract

The objective of this study aimed at determining the prevalence and antibiotic resistance of E. coli isolated from 120 samples (60 chicken meat and 60 pork samples) which were collected from 4 retail markets in Gia Lam district, Ha Noi City. The studied results showed that chicken meat and pork
were contaminated with E. coli at very high rate of 96.7% and 83.3%, respectively. All the isolates were resistant to at least 1 antibiotic, resistance was most common to tetracycline (96.3%) and erythromycin (92.6%). The majority of isolated strains (91.7%) were resistant to 3 or more antibiotics.
More than a half (52.8%) of isolates were capable to produce ESBL. The rate of gen blaCTX-M, blaTEM, and blaSHV of E. coli strains having ESBL phenotype was 78.9%, 35.1%, and 12.3%, respectively.
