Miller RP, Berlouis ME, Hall AG, Simpson AHRW, Smith IDM, Hall AC. Furthermore, concentration below the Minimum Inhibitory Concentration of -lactams and, to a lesser extent, vancomycin have been shown to enhance PVL secretion, determining more aggressive symptoms [7, 30].

PVL can be produced by both. The toxin Panton-Valentine Leukocidin (PVL) is a virulence factor produced by some strains of Staphylococcus aureus (S. aureus, SA) that destroys leucocytes. PVL-SA predominantly results in skin and soft tissue infections (SSTIs) but may also cause invasive disease, including necrotising pneumonia, which may affect healthy young individuals and has a high mortality.
