Community-associated Methicillin-resistant Staphylococcus aureus, Singapore

摘要

To the Editor: Community-asso-ciated methicillin-resistant Staphylo-coccus aureus (CA-MRSA) is anemerging phenomenon that has beenreported from almost every continentin the world (1–4). Such strains areusually characterized by multisuscep-tibility to non-β-lactam antimicrobialdrugs, production of Panton-Valentineleukocidin (PVL), and presence ofstaphylococcal chromosome cassettemec (SCCmec) IVa, a novel smallervariant of the methicillin-resistancelocus (5). The genetic backgrounds ofCA-MRSA strains from differentparts of the world are distinct and spe-cific for each geographic region(1–5).
