Abstract:
Objective To study the drug resistance of Staphylococcus aureus in 2006 -2011 ,and to provide the evidence for treatment infection .Methods The isolated bacteria were identified and antibiotic sensitivity were tested by automated system in 503 Staphylococcus aureus collected from 2006 to 2011 .Methicillin resistant Staphylococcus aureus(MRSA) was screened by oxacillin disk diffusion .Results 503 strains mainly derived from secretion and sputum .The incidence of MRSA was 44 .9% during 6 years . Detection rate of MRSA was decreased year by year .The difference was statistically significant between 2009 ,2010 ,2011 and 2006 , 2007 ,2008(P<0 .05) .No resistance to quinupristin/dalfopristin ,linezoiid ,vancomycin and nitrofurantoin was found .The resistance of Staphylococcus aureus was below 30% to levofloxacin ,imipenem ,compound sulfamethoxazole and rifampicin ,above 80% to ce-fazolin and penicillin .Although the resistant to cefazolin ,levofloxacin ,imipenem was risen ,the resistant rate of rest antibiotics was downed year after year .Conclusion Monitoring of drug resistance should be strengthened .The antimicrobial therapy should be de-fined on the basis of drug-sensitive test in order to control the incidence of infection and to delay the growth of clinical resistant strains of Staphylococcus aureus .
