BACKGROUND: The toxin Panton-Valentine leukocidin (PVL) produced by S. aureus is known as a virulence factor that leads to severe infections of skin and soft tissue. However the effect of PVL on wound healing is not known yet. Therefore we examined the detection rate of PVL in patients with chronic wounds. PATIENTS AND METHODS: The study included 100 patients with chronic wounds of the lower limb. We determined in all S. aureus isolates the presence of the PVL gene using a PCR technique. RESULTS: Altogether 94% of the patients had a leg ulcer, while 6% had a foot ulcer; 65% were women. PVL was found in two patients. One of the strains was methicillin-resistant (MRSA) and the other was methicillin-sensitive (MSSA). CONCLUSION: In our investigation there was detection rate for PVL of 2% of all S. aureus isolates in patients with chronic wounds of the lower extremities. Although the role of PVL as a virulence factor of S. aureus in wound healing remains unclear, the detection of PVL should be taken as a cause for a consequent topical antimicrobial wound therapy because of the increased risk of serious infections.
