*Antimicrobial drug susceptibilities were obtained from submitting institutions (unavailable for BK18505 and BK21466). PFGE was performed by using Cfr9I, with patterns assigned on the basis of 80% similarity cutoffs (BioNumerics version 6.5, Applied Maths, Austin, TX, USA); BK13684 and BK23527 were unavailable for PFGE analysis. spa typing was performed by using eGenomics software (, and Ridom spa types were assigned by using the SpaServer Web site ( Multilocus sequence typing was performed as described ( PFGE, pulsed-field gel electrophoresis; spa, staphylococcal protein A; ST, sequence type; wound, skin and soft-tissue infections from unspecified body sites; PEN, penicillin; CLI, clindamycin; ERY, erythromycin; OXA, oxacillin (resistance >4 μg/mL was reported for BK23527, but mecA was not detected by real-time PCR).
