| Sumario: | This study investigated the prevalence and the susceptibility profile of Staphylococcus aureus samples isolated from clinical infections in a teaching hospital, Paraná - Londrina, cases between 2001 and 2004. The sensitivity test results for 74 strains to oxacillin and vancomycim, obtained by MicroScan® automated system (Dada Bering, Sacramento, California, USA, employing MicroScan® PC 12- gram positive Panels) were compared with the results obtained from the dilution agar method using different concentrations of antimicrobials. The data was obtained from the Hospital Infection Committee Control Data bank. The Staphylococcus aureus samples showed a large spectrum of resistance to the antimicrobials tested. The medium rate of prevalence of the S. aureus hospital infections was 16,3% and the medium rate of prevalence of the hospital infection, by oxacillin resistant S. aureus strains was 70,75%. It was not detected samples resistant to vancomycin using both methods. Among this 74 samples identified as oxacillin-resistant by MicroScan® system, 65 (83,75%) had their resistance confirmed by Dilution Agar Method. The difference between the results was not statistically significant. To the vancomycin, there was 100% of concordance in both methods. |
