One-hundred strains of methicillin-resistant Staphylococcus aureus (MRSA) isolated from hospitals located in different areas in Japan were tested for antiseptic-resistance and the possession of transferrable antiseptic-resistant plasmid. The coagullase types of MRSA strains were type II (74%), type IV (11%), type VII (8%), type III (2%) and non-type (5%). Sixtyone strains were penicillinase-producing and 39 were non-producing. Antiseptic-resistant MRSA strains were isolated from 50 hospitals in different areas in Japan. The transferrable gentamicin-resistant plasmids were detected from 23 of the harboured strains. The antiseptic-resistant determinant was located on the transferrable gentamicin-resistant plasmid in 12 of the 23 strains. These 12 strains harbouring the transferrable antiseptic-resistant plasmid were isolated from all areas of Japan except for Hokkaido and Okinawa. The antiseptic-resistant strain and the strains harbouring the transferrable antiseptic-resistant plasmid were found not to exist in any specific hospital or area in Japan.
