Objective: In this study we aimed to evaluate the antibiotic susceptibility of staphylococci isolated from different clinical materials.
Study Design: From January 1999 to January 2000 the antibiotic susceptibility of staphylococcal strains isolated from different clinical materials at Sisli Etfal Training and Research Hospital was determined by disc diffusion test.
Results: Totally 257 ( 7.17% ) staphylococci were isolated out of the 3582 samples sent by different clinics. Among the 257 staphylococcal strains , 73 ( 28.4%) were coagulase positive (S.aureus), 184 ( 71.6 %) were coagulase negative. Among the evaluated 73 S. aureus strains 38 (52.1%) were found to be oxacillin resistant and 35 (47.9%) were oxacillin susceptible. Among the evaluated 184 coagulase negative staphylococci 110 (59.8%) were found to be oxacillin resistant and 74 (40.2%) oxacillin susceptible. All staphylococci were susceptible to glycopeptides. Conclusions: In order to prevent the development of resistance to glycopeptides among staphylococci in the future, the infections caused by these microorganisms should be treated by proper antibiotic.
