Objective To summarize the characteristics of nosocomial pulmonary infection in methicillin-resistant Staphylococcus aureus (MRSA) and the efficacy of vancomycin. Methods Sixty-nine cases of pulmonary infection in the hospital for MRSA were analyzed in the past four years. The related susceptibility factors, susceptibility testing, antibiotic use and therapeutic effect were studied. Results All 69 patients had severe underlying diseases, artificial airway, mechanical ventilation, antibiotic abuse and immunocompromise. MRSA is 100% sensitive to vancomycin, with higher sensitivity to trimethoprim and rifampicin, with minimal sensitivity to the remaining antibiotics. Vancomycin treatment is effective. Conclusions There are definite and susceptible factors in pulmonary infection in MR SA hospital. Vancomycin is the treatment of choice
