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.
