Panton-Valentine leukocidin (PVL) is a necrotizing exotox-in produced by both methicillin-susceptible and methicillin-resistant Staphylococcus aureus (MRSA) strains. a collection of pus just below the skin; painful, swollen, hot and tender to touch. Although PVL was found among several staphylococcal genotypes, it was slightly overrepresented in AFLP cluster IVb (CC 121) compared with major clusters I and III.
