Abstract
Recently the isolation of Methicillin-resistant Staphylococcus aureus (MRSA) is increasing in Oral Surgery in Japan. MRSA is one of the most important microorganisms which shows poor sensitivity to antibiotics and causes nosocomial infections.
To investigate the state of MRSA in the ward of Oral and Maxillofacial Surgery, a clinical study on MRSA isolated from medical staffs, inpatients and hospital environments was carried out. Two of the 21 doctors (10%) and one of the 7 inpatients (14%) had MRSA in the nasal cavity. However, none of the 9 nurses had MRSA in the nasal cavity. As to the hospital environments, MRSA was isolated only from the environment of the patients with MRSA infections.
This study revealed that the control of nosocomial MRSA infection was good in our ward, but a few MRSA carriers of medical staffs and inpatients exist. It seems to suggest that the state of microorganisms in the ward should be investigated at regular intervals.
