Recombinant Panton-Valentine leukocidin (PVL) toxins showed lytic activity against human (but not murine) neutrophils. The lytic activity of culture supernatants of USA400 and USA300 strains of MRSA were completely neutralized by anti-PVL monoclonal antibodies. In contrast, phenol-soluble modulin alpha3 (PSM) failed to lyse human neutrophils but did enhance PVL-mediated neutrophil lysis.
