The wide use of antibiotics and development of new broad-spectrum antibiotics have resulted in serious drug resistance of bacteria, which is one of the important public health problems in the globe. Nosocomial infection of methicillin-resistant Staphylococcus aureus (MRSA) is common and duo to its multi drug resistance and proneness to spread, the treatment of MRSA infection is diffucult.
