ABSTRACT
Objective To retrospectively analyze the drug resistance evolution of Staphylococcus aureus and MRSA,to provide the basis for prevention and control measures.Methods 576 strains of clinical isolated Staphylococcus aureus from 2009 to 2012 were analyzed.The bacteria identification and drug sensitivity test were detected by VITEK 2 Compact automatic bacteria identification instrument.Results The separation rate of MRSA from 2009 to 2012 was 59.5%,but the separation rate was gradually decreased per year.The antibacterial activity of MRSA was better to vancomycin,linezolid,quinupristin/Dalfopristin,teicoplanin,nitrofurantoin (resistance rate < 2.4%).The resistance rate and sensitive rate of MRSA to tigecycline was 0.0%,intermediary rate was 100.0%.The resistance of MRSA to gentamicin,ciprofloxacin,moxifloxacin,clindamycin,tetracycline and erythromycin was gradually decreased.From 2010 to 2012,The resistance of MRSA to cotrimoxazole decreased significantly,from 65.3% in 2010 to 28.2% in 2011 and 4.7% in 2012 (P < 0.05).Conclusion Separation of MRSA and drug resistance is reduced year by year,we should continue to strengthen the administration of antimicrobial agents,scientific and reasonable application of antibacterial drugs,reduce the incidence of multiresistant bacteria and drug resistance.
