Abstract :
Yersinia enterocolitica is a foodborne pathogen that causes gastroenteritis in humans. This bacterium enters the body through the consumption of contaminated food and exerts its harmful effects. The aim of the present study was to determine the prevalence of Yersinia enterocolitica and the determination of antibiotic resistance patterns of the isolates in chicken and turkey meat sold in Najafabad County, Isfahan. A total of 100 samples, including 50 chicken meat samples and 50 turkey meat samples, were randomly collected from meat supply centers and transferred to the Food Safety Laboratory of Islamic Azad University in Shahrekord. Yersinia enterocolitica isolates were identified and isolated through culturing and diagnostic tests. The antibiotic resistance pattern was determined using the disk diffusion method. The results showed that out of 100 samples of chicken and turkey meat, 22% were contaminated with Yersinia enterocolitica. A significant relationship was observed between the prevalence of Yersinia enterocolitica contamination in chicken and turkey meat (P<0.05). The highest resistance was observed against ampicillin, cephalothin, and amoxicillin, with resistance rates of 20%, 18%, and 14%, respectively, while the lowest resistance was related to ciprofloxacin, gentamicin, and chloramphenicol. Statistical analysis indicated that there was no significant relationship between the highest and lowest resistance. Given the high prevalence of antibiotic resistance, it is recommended that the use of antibiotics for the treatment of gastroenteritis caused by Yersinia enterocolitica be limited.
