[Homology analysis of the epidemiological strains of meticillin-resistant Staphylococcus aureus and the strains isolated from the nasal fossa of the medical staff and inpatients].
OBJECTIVE
To investigate the relation between the epidemiological strains of meticillin-resistant Staphylococcus aureus (MRSA) and the strains isolated from the nasal fossa of the medical staff and inpatients.


METHODS
The MRSA strains were isolated from the nasal fossa of the medical staff and inpatients in the Department of Neurosurgery. The genes of the isolated strains were amplified by randomly amplified polymorphic DNA (RAPD) assay.


RESULTS
Three and 12 MRSA strains were isolated from the nasal fossa of the medical staff and patients who were hospitalized for more than 1 week, respectively, and RAPD assay revealed high homology between the isolated strains.


CONCLUSIONS
Cross infection can be present between the medical staff, inpatients, and the infected patients.
