Methicillin-resistant Staphylococcus aureus in community-acquired meningitis

Abstract

We report two children with acute bacterial meningitis due to community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) who were admitted to the Pediatric Hospital of Posadas. Both isolates were identified using standard biochemical methods. Antimicrobial susceptibility testing was performed using disk diffusion tests as recommended by the Clinical and Laboratory Standards Institute . Methicillin resistance was confirmed by detection of the mecA gene by PCR. Both CA-MRSA isolates were susceptible to all non-â-lactam antibiotics. Both strains harbored the PLV gene and SCCmec type IV. Emergence of PLV-positive CA-MRSA causing meningitis in pediatric patients requires further control measures.
