Severe sepsis, combining acute osteomyelitis and lung involvement, has been described increasingly in healthy children with the spread of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA). ⋯ In this model, both PVL and Hla seemed to be required for early lung involvement via hematogenous spread. Hla, but not PVL, significantly impacted severe sepsis-related mortality. PVL was the predominant factor determining late-stage bone abscesses.
