title: [An epidemiological study of methicillin-resistant Staphylococcus aureus (MRSA) isolated from medical staffs, inpatients and hospital environments at our hospital].
abstract: Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most important microorganisms which is causative of the nosocomial infections. Recently the incidence of isolation of MRSA is increasing from year to year in Japan. Especially MRSA isolated from inpatients are much higher than from outpatients. Therefore we have done epidemiological studies about MRSA isolated from medical staffs, inpatients and hospital environments in our hospital. Thereafter we examined phage typing and coagulase typing of those MRSA. MRSA were isolated more frequently from anterior nares of inpatients in compare with doctors and nurses. MRSA were isolated more frequently from the environments of MRSA carriers. Coagulase type II and phage type N.T. (not typable) were dominant type of MRSA in our hospital (69% and 61%). Our studies have revealed that the isolation frequency of MRSA is very high in our hospital. It seems to suggest that inpatients who are carrying MRSA are spreading MRSA out hospital environments and medical staffs.
