Abstract
Staphylococcus aureus is one of the most important pathogens of the various infectious diseases. Recently, methicillin-resistant Staphylococcus aureus (MRSA)has been increasing and is becoming a serious clinical problem because of difficulties in it causes anti microbial chemotherapy and nosocomial infections. In this study, we endeavored to isolate MRSA from one hundred children who had no previous illness other than dental disease.
1. Ten percent of them were MRSA positive. The rate of MRSA carriers has increased about five times during the past five years.
2. All of the isolated MRSA showed resistance against all of the β-lactams. Only vancomycin was effective for all isolates.
3. There were no identical strains of isolates found based on the analysis of the biological typings. This result suggested these carrier children were not infected with MRSA in our clinic.
Our study revealed that the rate of carrier children was 10.0%, and it has increased in recent years. We will need to be more careful with nosocomial infections.
