[CA MRSA in furunculosis: case report of southern Brazil]. / CA-MRSA em furunculose: relato de caso do sul do Brasil.

Methicillin-resistant Staphylococcus aureus (MRSA), particularly isolated at hospital setting, has been identified in cutaneous infections of community patients. This paper reports a case of furunculosis from the southern Brazil. Dermatologists must be attentive to this emergent etiological diagnosis. The isolated microorganism was subjected to PCR for gene mecA and to PCR for the gene that encodes the leukocidin of Panton-Valentine. These exams enabled genotypic identification of CA-MRSA.
