Objective – To carry out a survey of positivity in blood cultures for Staphylococcus Coagulase Negative isolates, contemplating the most prevalent species and the antimicrobial resistance profile, analyzing the occurrence of contamination during the pre-analytical phase or a bacteremia, in a Public Hospital in the city from Bauru-SP. Methods – This is a retrospective study through the collection of data from the hospital's electronic medical record, which were statistically analyzed. Results – A prevalence of Staphylococcus epidermidis bacteria was found among the positive blood cultures observed in 285 patients, 55% of whom were male, with a rate of 80% of resistance of these microorganisms to the antimicrobials oxacillin and cefoxitin, however it was found 100% of sensitivity to vancomycin. Conclusion – Although two samples of positive blood cultures are needed for the diagnosis of bacteremia, in this study it was found that patients in critical condition and with symptoms of bloodstream infection with only one positive blood culture sample received antimicrobial treatment so as not to worsen the condition of the patient.
