Methicillin-resistant Staphylococcus aureus is the cause of nosocomial infections leading to high mortality. This cross-sectional study was conducted to study a total of 200 clinical specimens from Iranian military hospitals in 2013-2015. Disk agar diffusion test using cefoxitin disk (30 µg) showed methicillin resistance in 59% of our isolates. mecA and femB genes were identified in all of the MRSA isolates using PCR method. Our results demonstrated the spread of HA-MRSA isolates in the community and propagating CA-MRSA isolates in the studied hospitals.
