Abstract :
The aim of this study was to investigate the genes of some staphylococcal enterotoxins and Panton-Valentine leukocidin and methicillin resistance of Staphylococcus aureus strains isolated from subclinical bovine mastitis. In this study, 60 S. aureus isolates were used and the genes were detected by PCR. seg-sei, sej, sec and seh genes were detected in eight (13.33%) isolates, six (10.00%) isolates, four (6.67%) isolates and three (5.00%) isolates, respectively. Sixteen (26.67%) isolates were found to harbor one or more toxin genes. None of the investigated isolates harbored sea, seb, sed, see, and tsst genes, while four (6.6%) isolates and two (3.30%) isolates had Panton-Valentine leukocidin gene and mecA gene, respectively. As a conclusion, it was determined that S. aureus strains isolated from cows with subclinical mastitis could produce enterotoxin and harbor mecA gene. This situtiation could be a potential risk factor for public health.
