Abstract: 

Background: Because of the rapid development and spread of antimicrobial resistance, it is important to monitor antimicrobial resistance in pathogenic zoonotic and commensal bacteria of animal sources. In this study, the prevalence of antimicrobial resistance among commensal Escherichia coli isolated from fecal samples of sheep slaughtered at Kermanshah abattoir was investigated.
Methods: 100 fecal samples were collected form sheep slaughtered at Kermanshah abattoir during summer and fall seasons. Samples were cultured on EMB agar and obtained colonies were confirmed as Escherichia coli based on the biochemical tests results. Totally 85 isolates were obtained out of 100 fecal samples. Isolates were tested for antimicrobial agent susceptibility to 10 antibiotics (colistin, gentamicin, tetracycline, trimethoprim-sulfamethoxazole, amoxicillin-clavunic acid, enrofloxacin, ampicillin, cephotaxime, neomycin and florfenicol), using disc diffusion method.
Results: 92/94% (n=79) of isolates were resistant to at least one of the antimicrobials. 64/7% (n=55) of isolated E. coli were multidrug resistant and the highest resistance rate was detected for Tetracycline (76/5%) and Ampicillin (75/3%). No resistance was detected against Gentamicin and florfenicol. Conclusion: In conclusion, this study demonstrates that the prevalence of antimicrobial resistance to some of the antimicrobials is high among E. coli isolated from fecal samples of sheep slaughtered at Kermanshah abattoir (west of Iran) and this can be a crucial issue for both of human and livestock health.
