*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 (www.egenomics.com), and Ridom spa types were assigned by using the SpaServer Web site (www.spaserver.ridom.de). Multilocus sequence typing was performed as described (http://saureus.mlst.net). 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).
†BK27037 has been described (7).
‡Manhattan, Staten Island, and the Bronx are boroughs of New York, New York.
§Laboratory A is a large outpatient commercial laboratory serving the metropolitan New York, New York, area.
