Drug sensitivity analysis of Enterococcus faeciumand Enterococcus faecalis isolates from 2011 to 2013

Objective To explore the sensitivity of Enterococcus faeciumand Enterococcus faecalis isolated from 2011 to 2013and 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 faeciumto Enterococcus faecalis isolates was 1.93 and it was increasing year by year.No vancomycin,linezolid and tigecycline resistant Enterococcus faeciumand Enterococcus faecalis isolates was detected.The rates of Enterococcus faeciumsensitive to quinupristin-dalfopristin and tetracycline were higher than Enterococcus faecalis(P0.05),and the rates of Enterococcus faeciumsensitive to nitrofurantoin,ampicillin,penicillin G,moxifloxacin,levofloxacin and ciprofloxacin were lower than that of Enterococcus faecalis(P0.05).Conclusion The detection rates of Enterococcus was shifting to Enterococcus faecium,and the trends became obvious year after year.The drug sensitivity of Enterococcus faeciumand Enterococcus faecalis is different,and doctors should choose the proper therapy according to their specific drug resistance.At present,vancomycin,linezolid and tigecycline are preffered for the treatment against infection caused by Enterococcus faeciumand Enterococcus faecalis.
