Outline of Final Research Achievements

The separation rate of methicillin-resistant Staphylococcus aureus (MRSA) is regarded as an indication of whether or not infection control measures are sufficiently conducted in medical institutions. In recent years, it has become possible to judge whether or not the origins of separated MRSAs are identical by genetic testing. We conducted MRSA genetic tests separated by medical institutions in Nagano Prefecture and conducted a survey of the propagation pattern of MRSA in Nagano Prefecture.
Nagano prefecture can be broadly divided into 4 districts. The isolated MRSA was found to have a large number of identical-derived strains propagated in specific areas. In regions where transmission of identical strains is frequent, the separation rate of MRSA is high, and horizontal transmission of MRSA should be dealt with as regional problem.
