Staphylococcus aureus is the commonly encountered pathogen isolated from clinical specimens. Methicillin resistant Staphylococcus aureus (MRSA) causes variety of human infections resulting in high rate of mortality and morbidity. The aim of the study was to screen for MRSA by disc diffusion method using cefoxitin and oxacillin discs and to determine antimicrobial susceptibility and resistance of Staphylococcus aureus. Two hundred Staphylococcus aureus were isolated from samples like pus, blood, sputum, vaginal swab, urine and body fluids received in microbiology department of Coimbatore medical college hospital. They were confirmed by microscopy, culture and biochemical reactions. MRSA were detected by disc diffusion test using cefoxitin (30μg) and oxacillin (1μg) discs. Majority of Staphylococcus aureus were isolated from pus samples (87.5%). Isolated Staphylococcus aureus strains were highly sensitive to linezolid (100%) and vancomycin (99%) and 100% resistant to penicillin. Cefoxitin disc detected higher percentage (26%) of MRSA than oxacillin disc (24%). Detection of MRSA is considered as very important for treating patients and to prevent its spread.
