Abstract

Background/aim: Staphylococcus aureus colonization is a determiner of disease activation in psoriasis patients. Here we evaluatethe presence of genes encoding Panton-Valentine leukocidin (PVL), enterotoxins, TSST-1, exfoliative toxins, and the accessory generegulatory locus by polymerase chain reaction (PCR) in S. aureus isolates obtained from healthy and diseased skin regions and anteriornares of psoriasis patients and healthy controls.Materials and methods: The presence of PVL and toxin genes was investigated, and agr typing was performed by PCR. Results: Eighteen of the isolated strains carried the sei, 1 carried the seb-sec, and 1 carried the seg enterotoxin gene. Eight of the strainscarrying enterotoxin genes were isolated from nasal swabs, 6 from diseased skin swabs, and 4 from healthy skin swabs. None of thestrains isolated from the control group carried the agr locus. On the other hand, 11 of the S. aureus strains isolated from the patientscarried type 1, 7 carried type 1 + 3, 4 carried type 2, 4 carried type 3, and 1 carried type 1 + 2 agr loci. Conclusion: Enterotoxin production and the carried accessory gene regulatory locus may be important in the aggravation of psoriasis.
