Abstract: Objective To investigate the characteristics of distribution and the changes in drug resistance of Enterococci,providing reference for clinical treatment.Methods The distribution and drug resistance in 2547 clinical isolates of Enterococci from 2001 to 2007 in Huzhou Central Hospital and the First People's Hospital of Huzhou were retrospectively analyzed.Results A total of 2547 strains of Enterococci were isolated from 94876 clinical specimens(2.68%),in which Enterococcus faecalis wag primary and Enterococcus faecium Wag ranking the second.The positive rate of Enterococci in urine specimens was the highest,and that in sputum specimens was increasing recently.Enterococci showed higg resistance to erythromycin,rifampin,ciprofloxacin and levofloxacin;Enterococcus faecalis Wag more sensitive to penicillin,ampiciilin and ndtrofurantoin than Enterococcus faecium,while Euterococcus faecium was more sensitive to chloramphended and tetracycline than Enterococcus faecalis;both of them were sensitive to vaneomycin and teicoplanin.Conclusions Enterococcus faecalis and Enterococcus faecium are the common pathogen in Enterococci infections.Enterococci show high drug resistance,so the clinical use of antibiotics should be based on the resuhs of drug sensitivity test.
