PREVALENCE AND ANTIBIOTIC SUSCEPTIBILITY OFSTAPHYLOCOCCUS AUREUS IN ICU BLOOD

Abstract

This investigation investigated the drug susceptibility and prevalence of Staphylococcus aureus which were isolated from blood samples in the ICU. Conventional microbiological techniques were employed to analyze blood culture-positive samples for Staphylococcus aureus, and the Kirby–Bauer disk diffusion method was employed to evaluate antibiotic susceptibility in accordance with the Clinical and Laboratory Standards Institute (CLSI) guidelines. Cefoxitin discs have demonstrated resistance to methicillin. The intensive care unit's predominant bloodstream isolate was Staphylococcus aureus, including MRSA, according to the study. The bacteria were susceptible to vancomycin and linezolid, but they were resistant to penicillin and erythromycin. The critical significance of antibiotic stewardship in intensive care units is underscored by the multidrug resistance of Staphylococcus aureus.
