Abstract: Linezolid is a drug of choice for the treatment of methicillin resistant Staphylococcus aureus (MRSA) infections. However, resistance to this antibiotic have been reported. This study has been conducted to determine linezolid resistance among MRSA. A descriptive study was conducted in microbiology department. In the present study a total of 150 Staphylococcus aureus (S. aureus) were subjected to antibiotic susceptibility test by Kirby Bauer disc diffusion method as per CLSI guidelines. The detection of MRSA was done by cefoxitin disc (30μg) and linezolid disc (30μg) was included to detect its susceptibility. The prevalence MRSA was reported as 73 (48.7%) and linezolid and vancomycin were found to be 100% sensitive in the present study. The sensitivity against penicillin was found to be the lowest i.e. 7.3%. It could be concluded from the findings of the present study that linezolid is still the preferred drug for the treatment of infections caused by MRSA
