Abstract: 

Staphylococcus aureus is a gram-positive coccal bacterium of the micro cocaceae family and by the release of toxins such as enterotoxins provides invasion to the host. The aim of this study was to identify enterotoxin genes of Sea, Seb, Sec and Sed in Staphylococcus aureus isolates of human skin infections and ewes with subacute mastitis. In this study 110 suspected S. Aureus isolates were collected from Chaharmahal and Bakhtiari province, the isolates were confirmed using microbiological standard methods. Then the PCR test was performed on 67 samples using specific primers to identify mentioned genes. The results showed that within 38 samples of human skin infections 19 cases were positive for Seb and Sea genes. 7 cases had Seb gene (18.42%). And 12 samples (31.58%).) were positive for Seagene. Within29 samples of ewe subacute mastitis 13 cases were positive for Sea, Seb, Sec and Sed genes. 5 samples had Sea gene (17.24%), 4 were positive for Seb (13.79%), 3 were positive for Sec (10.34%) and 1 had Sed gene (3.45%). Results were confirmed by sequencing and showed a high percentage of Staphylococcus aureus isolated from clinical specimens had enterotoxin genes. Given the importance of these toxins produced by pathogenic strains, if the expression of these genes occurs, early treatment of infection would be necessary.
