Community-acquired methicillin-resistant Staphylococcus aureus infections: An emerging threat in Spain

Abstract

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has not been recognised previously as a cause of MRSA infections in Spain. Nineteen patients carrying Panton-Valentine leukocidin (PVL)-positive MRSA were identified in a Barcelona hospital, of whom 15 were immigrants, mostly from South America. Twelve developed skin and soft-tissue infections. The associated isolates carried the PVL gene and staphylococcal chromosomal cassette (SCC) mec IV. A dominant clone belonging to sequence type (ST)8 and related to the USA300 clone was identified by pulsed-field gel electrophoresis. This clone is emerging in Spain, primarily among immigrants from South America, but dissemination to the native Spanish population could increase. © 2008 European Society of Clinical Microbiology and Infectious Diseases.
