Abstract:
OBJECTIVE To investigate the antimicrobial-resistant profile of Staphylococcus aureus isolated from clinical specimens. METHODS The isolates of S.aureus were obtained from all kinds of clinical specimens by routine methods.The identification and susceptibility test of the isolates were determined by Automated Microbiology Analyzer.Disk-diffusion was used for detecting meticillin-resistant Staphylococcus aureus(MRSA). RESULTS The isolates were mainly isolated from sputa and urines.62.1% of isolates were referred as MRSA.All isolates of MRSA were resistant to ampicillin/sulbactam,penicillin G and cefazolin.No isolates of MSSA were resistant to above drugs.All isolates were susceptible to nitrofurantoin and vancomycin.The resistant rates of the isolates of MRSA to clindamycin,erythromycin,gentamicin,tetracycline,rifampin,sulfamethoxazole and levofloxacin were 70.7%,86.6%,87.8%,82.9%,42.7%,30.5% and 91.5%,respectively,those of MSSA were 31.3%,41.7%,20.8%,20.8%,10.4%,29.2% and 6.3%. CONCLUSIONS The antimicrobial resistance of MRSA is serious,but the antibiotics have high activity to the isolates of MSSA except penicillin G in vitro.Vancomycin has very high activity to the isolates of MRSA in vitro.
