Establishment of ST30 as the Predominant Clonal Type among Community-Associated Methicillin-Resistant <i>Staphylococcus aureus</i> Isolates in Singapore

Abstract

The number of infections attributable to community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in Singapore is progressively increasing. Most cases in the past 2 years were caused by Panton-Valentine leukocidin-positive isolates belonging to sequence type 30, according to multilocus sequence typing. This has clearly become the predominant sequence type among CA-MRSA isolates in Singapore.
