Prevalence, antimicrobial susceptibility and virulence genes of Staphylococcus aureus isolated from pork meat in retail outlets in India
JOURNAL OF FOOD SAFETY(2019)
Abstract
Isolation of Staphylococcus aureus was carried out in a total of 120 retail pork samples and the overall prevalence of S. aureus in retail pork meat was 76.67%. All the isolates were resistant to both Ampicillin and Tetracycline (100%) followed by Cefoxitin, Oxacillin, Erythromycin, Amoxicillin, and Novobiocin. The multiple antibiotic resistance index of majority of the isolates were 0.3 and above. Methicillin resistance based on polymerase chain reaction revealed that 76.09% carried either mecA or mecC. The prevalence of enterotoxigenic S. aureus in pork was 82.61% and of the various toxin genes sei was the major gene followed by seg, seb, sej, sed, seh, sec, and sea in decreasing order. The prevalence of multidrug resistant and virulent S. aureus carrying enterotoxin genes in retail pork meat is a clear indication of the potential of these isolates in causing foodborne intoxication under favorable conditions to the consumers.
