The Role of Panton-Valentine Leukocidin in Staphylococcus aureus Musculoskeletal Infections in Children

The Pediatric Infectious Disease Journal, 05/07/2012

Ritz N et al. – This review summarizes the current evidence on the influence of Panton–Valentine leukocidin (PVL) on musculoskeletal infections caused by S. aureus in children and highlights areas of uncertainty relating to management.

  • 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 reported in lung and bone infection, this is not the case for skin and soft tissue infection.
  • A number of recent reports describe severe complications associated with PVL-producing strains in musculoskeletal infections.
