| Research Abstract |
To investigate prevalence in Japan of community-acquired MRSA (CA-MRSA) which is concerned for its global spread, and their molecular epidemiological characteristics, we analyzed clinical isolates from the Sapporo Medical University Hospital (601 isolates, 2008-2010) and those from local hospitals/clinics in Hokkaido prefecture (outpatients, 422 isolates in 2011). As a result, SCCmec types IV and V, which are genetic markers of CA-MRSA, were detected in 4.3% and 17.1% in the isolates from the University Hospital and local hospitals/clinics, respectively. Among them, seven isolates were revealed to be USA300 clone which is dominant in the US (ST8, positive for PVL and ACME), and many ST5 MRSA having ACME were detected. These emerging CA-MRSA clones were confirmed to be distributed in Japan.
