OBJECTIVE To investigate the resistance of Staphylococcus aureus isolated from 2000 to 2004 to nine kinds of antimicrobial agents. METHODS Susceptibility test was performed by disk diffusion method and analyzed by software WHONET 5.3. RESULTS The 516 S.aureus strains showed resistant rates of 90% to penicillin,the percentage of resistance of S.aureus to the nine drugs increased with years,accounted for over 57.8% except for sulfamethoxazole/trimethoprim and vancomycin in 2004.The isolated rate of MRSA was 44.8%.The resistance of MSSA to penicillin and erythromycin was 86.6% and 55.1%,respectively.None of the isolates showed (resistance) to vancomycin. CONCLUSIONS There is an increasing trend of isolated rate and resistance in S.aureus.MRSA strains are multidrug resistant.
