[Emergence of methicillin-resistant Staphylococcus aureus SCCmec type IV/V epidemic clones in a large teaching hospital in China].

Objective: To investigate the staphylococcal cassette chromosome (SCC) genotype and molecular epidemiological characteristics of healthcare-associated methicillin-resistant (HA-MRSA) in a large teaching hospital in China.

Methods: From January 2012 to December 2012, a total of 71 nonduplicate HA-MRSA were collected in a teaching hospital in Changsha, China. SCC types were determined by multiplex PCR, and Panton-Valentine leukocidin (PVL) gene was detected by PCR.
