Objective: To characterize the clinical distribution and drug resistance of hospital-acquired infections due to Enterococcus spp and provide basis for clinical treatment. Methods: The clinical data of hospital-acquired enterococcus infection patients from 2013.1 to 2015.12 in Chinese PLA General Hospital were retrospectively analyzed. Results: A total of 883 strains of Enterococci were isolated in this study. Most of them were isolated from ICU (292 strains, 33.07%) and hepatobiliary surgery department (125 strains, 14.16%); Urine was the most common sources of these strains (347, 39.30%), followed by body fluids (315, 35.67%) and blood samples (202, 22.88%); The top organism was Enterococcus faecium (596, 67.50%), followed by Enterococcus faecalis (244, 27.63%). The resistance rates of Enterococcus faecium to ampicillin, penicillin, streptomycin, tetracycline, erythromycin, vancomycin and ciprofloxacin were obviously higher than Enterococcus faecalis (P<0.05). Conclusions: Enterococcus faecium and Enterococcus faecalis are the main pathogens in hospital-acquired enterococcus infection, and Enterococcus faecalis has higher resistance rate. It's necessary to choose the appropriate antibiotics according to drug susceptibility test in clinical treatment.
