Drug sensitivity analysis of Enterococcus f aecium and Enterococcus f aecalis isolates from 2011 to 2013 / 国际检验医学杂志

ABSTRACT

Objective To explore the sensitivity of Enterococcus f aecium and Enterococcus f aecalis isolated from 2011 to 2013 and provide reference for anti-infection therapy .Methods The identification and drug sensitivity test of clinical isolates were carried out by using VITEK2 Compact system .Results The ratio of Enterococcus f aecium to Enterococcus f aecalis isolates was 1 .93 and it was increasing year by year .No vancomycin ,linezolid and tigecycline resistant Enterococcus f aecium and Enterococcus f aecalis i-solates was detected .The rates of Enterococcus f aecium sensitive to quinupristin-dalfopristin and tetracycline were higher than En-terococcus f aecalis(P<0 .05) ,and the rates of Enterococcus f aecium sensitive to nitrofurantoin ,ampicillin ,penicillin G ,moxifloxa-cin ,levofloxacin and ciprofloxacin were lower than that of Enterococcus f aecalis(P<0 .05) .Conclusion The detection rates of En-terococcus was shifting to Enterococcus f aecium ,and the trends became obvious year after year .The drug sensitivity of Enterococcus f aecium and Enterococcus f aecalis is different ,and doctors should choose the proper therapy according to their specific drug resist-ance .At present ,vancomycin ,linezolid and tigecycline are preffered for the treatment against infection caused by Enterococcus f aeci-um and Enterococcus f aecalis .
