Abstract
The prevalence and resistance of Campylobacterjejuni in small ruminants in Jordan to antimicrobials of human clinical importance and the management factors that associate with C. jejuni in the flocks were determined. Flock-level prevalence of C. jejuni was 28.5%; individual animals’ prevalence was 11.0%. Flocks that reported abortions within the immediate last season had 2.7 × higher likelihood of C. jejuni occurrence than flocks that did not report abortions in the immediate last season. More than 75% of C. jejuni isolates were resistant to ampicillin, nalidixic acid, streptomycin, and erythromycin; the lowest resistance was toward amoxicillin-clavulanic acid. Overall, 70.1% of the isolates were multidrug-resistant (resistant to ≥3 antimicrobial classes); 51.7% were resistant to ≥5 antimicrobial classes. Sheep isolates generally showed significantly higher resistance percentages than goat isolates. The results highlight the probability of small ruminants as a source of campylobacteriosis in human and the importance of the heat treatment of milk.
