Abstract :

Poultry meat is considered as one of the sources of Escherichia coli O157. The present study was performed to evaluate the prevalence and antibiotic resistance of Escherichia coli O157 isolates of poultry meat samples presented in Isfahan. In total, 500 meat samples were collected from diverse poultry samples supplied in Isfahan and evaluated for the presence of Escherichia coli O157 using microbial culture. Suspicious isolates were confirmed by PCR test. The pattern of antibiotic resistance of isolates was investigated using the antibiotic disk diffusion test. Forty-four out of a total of 500 samples (8.80%) were contaminated with Escherichia coli O157. The highest level of contamination was related to duck meat (16%) and the lowest was related to quail meat (3%). There was a statistically significant difference of P
