Molecular analysis of 197 non-duplicate meticillin-resistant Staphylococcus aureus (MRSA) isolates collected from five acute care public hospitals in Singapore in May 2005 revealed that 66 (33.5 %) were EMRSA-15 while 121 (61.4 %) belonged to the endemic multidrug-resistant ST239 clone. Median and mode vancomycin MIC for both major clones of health-care-associated MRSA were relatively high at 2.0 μg ml−1. Subsequent laboratory surveillance data collected from the first half of 2006 confirmed increasing numbers of the EMRSA-15 clone – ranging from 25.0 to 66.1 % of all MRSA isolated in local hospitals – replacing the ST239 clone island-wide., UL https://www.microbiologyresearch.org/content/journal/jmm/10.1099/jmm.0.46950-0
