The incidence of methicillin resistance among nosocomial isolates of S. aureus is now higher than 60% in Korea (3).

Some epidemiological studies have suggested that most of CA-MRSA strains had association with lack of multi-drug resistance, predominance of staphylococcal cassette chromosome mec element (SCCmec) IV and high prevalence of Panton-Valentine leukocidin (PVL) 증 례
