Abstract:
The present study was conducted in a total of 120 samples collected from different parts of Udaipur city, Rajasthan in order to isolate and identify the S. aureus from milk, egg and meat samples. In total, 40 samples each of raw milk, egg and meat were processed for the isolation and identification of Staphylococcus aureus employing standard biochemical assays. All the samples were collected randomly from dairies, egg outlets and meat outlets located in different parts of Udaipur city, Rajasthan. Out of 120 samples analyzed, 19.17% (23/120) samples were found to be positive for S. aureus. Prevalence of S. aureus in raw milk, egg and meat samples was 37.5% (15/40), 5% (2/40) and 15% (6/40), respectively. In the investigation, all the isolates were subjected to antibiotic susceptibility test by using 12 different antibiotic discs. The analyses of antibiogram revealed that majority of the isolates were sensitive for amoxyclav (73.91%), ampicillin (56.52%) and gentamicin (56.52%). However, the isolates revealed higher resistance for methicillin (60.86%), co-trimoxazole (52.17%), oxytetracycline (52.17%) and streptomycin (52.17%).
