Objective: To investigate the antimicrobial resistance of staphylococcal isolates from 51 hospitals in 2000 in China. Methods:Antimicrobial susceptibility test was conducted by disk diffusion technique (K B method). Results:⑴ Resistance rates of MRSA, MRCNS isolates to ciprofloxacin, erythromycin, gentamicin, trimethoprim/sulfamethoxazole, tetracycline , chloramphenicol, and clindamycin were 76.0%, 91.0%, 72.0%, 55.0%, 72.0%, 44.0%, 74.0% and 55.2%, 82.0%, 32.2%, 77.4%, 58.8%, 45.1%, 52.7%, respectively. ⑵ The resistance rates of methicillin sensitive coagulase negative staphylococci (MSCNS) to ciprofloxacin, chloramphenicol, tetracycline and trimethoprim/sulfamethoxazole, were higher than those of methicillin sensitive S aureus (MSSA) MSCNS remains sensitive to most of antimicrobial agents routinely used in clinical practice including ciprofloxacin, gentamicin chloramphenicol and clindamycin, the resistance rates were 24.3%, 7.5%, 31.3%, 24.4%. Conclusions: It is important to monitor the antimicrobial resistance of staphylococcus species.
