Community-acquired methicillin-resistant Staphylococcus aureus carrying Panton-Valentine leukocidin genes: a lethal cause of pneumonia in an adult immunocompetent patient

Scand J Infect Dis. 2007;39(5):466-9. doi: 10.1080/00365540601034790.

Abstract

Necrotizing pneumonia and fatal septic shock were caused by Panton-Valentine leukocidin-positive, community-acquired, methicillin-resistant Staphylococcus aureus (CA-MRSA) in a previously healthy, 61-y-old female. This patient did not belong to any high-risk group (e.g. homosexuals, military recruits, sports team members, etc.). CA-MRSA infection should be suspected in any adult with severe pneumonia/sepsis.
