Abstract

A cross-sectional study was conducted to determine the prevalence, antimicrobial resistance profile and genotypic diversity of Campylobacter in swine herds. Over all, Campylobacter coli were the only species isolated from the study with a prevalence of 55.8% and 27.9% at farm and slaughter respectively. C. coli prevalence between the two ABF systems was not significantly different at farm (P=0.83). Highest frequency of resistance was seen against tetracycline (48.3%) and erythromycin (40.6%). We detected significantly higher proportion of C.coli isolates from the intensive system resistant to the above two antimicrobials at the finishing farms (P<0.001). Resistance against the fluoroquinolone ciprofloxacin was detected in isolates from farm and in both types of ABF herds (n=3).
