| Outline of Final Research Achievements |
Methicillin-resistant Staphylococcus aureus (MRSA) is drug-resistant bacteria known for a long time. Recently, two MRSA clones with novel genetic traits (①MRSA harboring SCCmec-IVl which is a novel genetic complex; ②Coagulase type-II MRSA having ACME which is a genetic complex related to attachment to human skin) have been reported. We investigated their prevalence in clinical isolates in Hokkaido, Japan. These MRSA ①, ② were detected in 3.5% and 5.1% of isolates from outpatients of community, and 3% and 0.9% of isolates from a university hospital, respectively. Genetic diversity was found in MRSA with ACME, and their spread in the community and hospitals was concerned.
