[Necrotizing pneumonia due to methicillin-resistant Staphylococcus aureus].

The aim of this study was to describe a case of necrotizing pneumonia caused by methicillin-resistant Staphylococcus aureus. The sample was isolated from a blood culture collected less than 48 hours after hospital admission. The patient had been healthy until the infectious process started. The isolate had the mecA gene with "staphylococcal cassette chromosome mec" (SCCmec) type IVa. The possibility that Staphylococcus aureus harboring this genetic determinant might be present in our setting should be considered in situations of severe pneumonia within the community.
