ABSTRACT
To observe the pattern of antibiotic resistance in methicillin sensitive and methicillin resistant staphylococcus aureus. Materials and Two hundred Staphylococcus aureus isolates from patients with hospital- acquired infections were collected. Methicillin resistance was determined by disc [oxacillin 1 micro g] diffusion method. Sensitivity to other antimicrobial agents was determined by Kirby Baurer disc diffusion method. The methicillin resistant Staphylococcus aureus isolates were found sensitive to vancomycin [100%], fusidic acid [88.5%], chloramphenicol [80.8%] and fosfomycin [61.5%]. All the isolates were highly resistant to other classes of antimicrobial agents. Methicillin resistant Staphylococcus aureus shows multi-drug resistance and infections caused by these isolates are difficult to treat. However our results show that beside vancomycin; fusidic acid, chloramphenicol and fosfomycin are good choices and should be tried for the isolates showing sensitivity to these agents
