Abstract： Objective To study the resistance of clinically-isolated Staphylococcus aureus to antimicrobial agents so as to facilitate the rational use of antibiotics. Methods The pathogenic bacteria were evaluated by VITEK32. Drug susceptibility test was carried out by K-B method. The results of 158 strains of Staphylococcus aureus were analysed by WHONET. Results 96 strains of MRSA were detected from 158 strains of Staphylococcus aureus ,which accounted for 60.76%. All the MRSA was resistant to penicillin and ampicillin but was sensitive to vancomycin. The resistance rate of MSSA to penicillin and ampicillin was 69.35% and 67.74%, respectively, and all the MSSA was sensitive to linezolid, quinupristin/dalfopristin and vancomycin. Conclusions Staphylococcus aureus is one of the main pathogens of clinical infection. Analysis of drug resistance of Staphylococcus aureus can guide the clinical use of antibiotics.
