Pneumonia and new methicillin-resistant Staphylococcus aureus clone

Emerg Infect Dis. 2006 Mar;12(3):498-500. doi: 10.3201/eid1203.051040.


Necrotizing pneumonia caused by Staphylococcus aureus strains carrying the Panton-Valentin leukocidin gene is a newly described disease entity. We report a new fatal case of necrotizing pneumonia. An S. aureus strain with an agr1 allele and of a new sequence type 377 was recovered, representing a new, emerging, community-acquired methicillin-resistant clone.
