PURPOSE Panton-Valentine Leukocidin (PVL) is an exotoxin produced by strains of Staphylococcus aureus (SA). Its importance as a virulence factor is controversial. We aim to further characterize the role of PVL in pediatric community-acquired SA infections. METHODS In a cohort study conducted from July to November 2006, we prospectively collected all strains of SA isolated at the Montreal Chil...
We determined the entire nucleotide sequence of phiSa2958-carrying Panton-Valentine leukocidin (PVL) gene, which was lysogenized in a sequence type 5 staphylococcal cassette chromosome mec (SCCmec) type II strain of methicillin-resistant Staphylococcus aureus (MRSA). Based on the nucleotide sequences of PVL phages, we developed PCRs to discriminate among five PVL phages, with a preliminary clas...
Infections caused by Panton-Valentine leukocidin (PVL)–producing strains of Staphylococcus aureus have been reported with increasing frequency. However, the role of PVL in the pathogenesis of invasive staphylococcal infection is controversial. It is interesting to note that the role played by PVL may depend on the site of infection; although an association between PVL and severity has been repo...
