ABSTRACT

A total of 50 chevon samples were collected from various meat shops of Bikaner city (Rajasthan) to examine the presence of Staphylococcus aureus and study antibiotic sensitivity pattern of isolated S. aureus. 46 (92%) samples were found to be contaminated with average counts of S. aureus 4.347 log 10 cfu/g. Half of the observed values to be in the potentially hazardous category. Among these 46 S. aureus isolates, 21 (45.65%) were coagulase positive. The results of antibiotic sensitivity tests revealed all S. aureus isolates (100%) sensitive to ciprofloxacin and doxycycline. In contrast, all isolates of S. aureus (100%) were resistant to ampicillin and cloxacillin. Moreover, S. aureus isolates were highly sensitive to gentamycin while most of the isolates were highly resistant to tetracycline and ofloxacin. Multidrug resistance was also found in most of the isolates. This study revealed high prevalence of S. aureus in raw chevon samples and also evidenced antibiotic resistance of the organism. The study reflects the poor hygienic condition of slaughtering and handling of chevon meat.
