Abstract: To describe the analysis of geographical and temporal distribution of DNA profiles determined by pulsed-field gel electrophoresis (PFGE) of methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from hospitalized patients in a tertiary care university hospital in Brazil. Ninetynine samples of MRSA obtained from 89 patients in the period 1999-2004 were studied. MRSA strains were isolated from central venous catheters (33 isolates) and bloodstream infections (66 strains). PFGE with 20 units of SmaI restriction endonuclease was used for genomic typing. Analysis of DNA PFGE of 99 strains of MRSA revealed 26 profiles and their respective related profiles. The mean time interval for detecting MRSA infection was 26 days from hospital admission. Forty-nine patients (57.6%) had a recent hospitalization. The DNA PFGE MRSA profiles were distributed in three clonal groups-I, II, and III-according to the period of time when the MRSA strains were isolated. DNA PFGE MRSA profiles were spread homogeneously through all hospital wards. Changes in the distribution of DNA PFGE MRSA profiles were largely temporal, with clonal groups being replaced over time, without predominance in any hospital ward or any specific area of the hospital.
