Background: Staphylococcus aureus is one of the most common nosocomial and community ‎acquired pathogens. The bacterium has different virulence factors and provides aggressive conditions ‎to the host with secretion of the toxins such as super antigenic enterotoxins. Staphylococcal enterotoxin ‎A and B (SEA,SEB) have the most severe toxic effect among these toxins. The aim of this study was ‎to determine the frequency of A and B enterotoxin genes in Staphylococcus aureus isolated from skin ‎infections in Tehran Razi hospital. ‎ Materials and methods: A total of 65 isolates of Staphylococcus aureus from skin samples were ‎collected and confirmed with phenotypic methods and checked by Polymerase Chain Reaction (PCR) ‎using species specific primers. Then the frequency of the sea and seb genes were detected with PCR ‎using specific primers. ‎ Results: The PCR results showed that 86.20 % of Staphylococcus aureus isolates carried the sea ‎gene and the frequency of seb gene in the tested isolates was 15.40 %. ‎ Conclusion: According to the importance of Staphylococcus aureus enterotoxins and their role in the ‎development and exacerbation of the staphylococcal diseases, the presence and expression of the ‎corresponding genes in clinical isolates must be considered in management of the diseases.‎ Keywords: Staphylococcus aureus, Enterotoxins A and B, Skin infections.‎
