Background and Aims: Since 1959, treatment of infections caused by S. aureus included semi synthetic penicillin drugs such as Methicillin. Sooner a year later in 1960 Methicillin resistant S. aureus came into existence. Decade after decade the MRSA strains increased and these bacteria were marked as major cause of nosocomial infections in early 1980s. The invasion of MRSA into community is now day's matter of concern for microbiologist. This study was conducted to detect the prevalence of MRSA resistance and to prepare antibiogram of HA-MRSA and CA-MRSA isolates at our hospital. Materials and Methods: A total of 201 staphylococcus isolates were detected as MRSA. They were then separated into two categories i.e. community acquired MRSA (CA-MRSA) and hospital acquired MRSA (HA-MRSA) according prescribed criteria. Antibiogram was prepared by Kirby- Bauer disk diffusion method. Results: Out of 201 isolates, HA-MRSA prevalence was 143(28.6%) and CA-MRSA was 58(11.6%). The HA-MRSA isolates showed were 10- 30% more resistant when compared to CA-MRSA. All isolates were 100 % sensitive to Vancomycin and Linezolid. Conclusion: We strongly suggest that time to time monitoring of MRSA should be done and proper hand wash must be done to avoid spread of MRSA.
