Community-acquired meticillin-resistant Staphylococcus aureus (CA-MRSA) is becoming an important public-health problem. This study attempted to investigate S. aureus and MRSA colonization in nasal swabs obtained from 843 patients without a history of hospitalization at the time of hospital admission and from 72 health-care workers chosen for comparison. Of the patients, S. aureus was detected in 218/843 (25.9 %) and MRSA in 17/843 (2.0 %). Of the health-care workers, S. aureus was detected in 15/72 (20.8 %) and MRSA in 10/72 (13.9 %). The majority of the 27 MRSA isolates exhibited a sensitivity pattern expected for CA-MRSA. Multilocus restriction fragment typing resolved the isolates into eight restriction fragment types. The predominant restriction fragment types were AAACCAA and AAAAAAA, accounting for 51.9 % (14/27) of the MRSA isolates and included CC5 and CC1 groups, respectively. This study thus demonstrated the transmission of CA-MRSA strain types into a health-care setting, emphasizing the need for implementation of a revised set of control measures in both hospital and community settings.
