Abstract:
Objective To discuss the distributional characteristics and drug-resistance of Enterococcus species isolated from urine specimens.Methods 3096 middle-segment urine specimens were collected since January to December in 2011 for culture.The identification of pathogenic bacteria and antibiotics sensitivity tests were carried out with VITEK2-compact combined with GN,AST-GN13,GP,AST-GP67,and antibiotics sensitivity tested performed by K-B and E-test at the same time.The results were determined by CLSI 2011.Results 1248 of 3096 pathogenic bacteria were isolated (40.31％).549 strains of Escherichia coli were detected (43.99％) which was the most common and 159 strains of Enterococcus were detected (12.74％) which was the second most common.The Enterococcus detection rate in woman (15.02％)was higher than that in man (10.35％),in out-patients (15.54％) than the that in hospitalized patients (12.49％),and in the patients of non-surgical departments (13.65％) than those of surgical departments (11.38％).The Enterococcus was absolutely sensitive to tigecycline,and the sensitive rate to vancomycin and linezolid were over 90％.The antibiotics sensitivity was higher for Enterococcus faecalis than that for Enterococcus faecium,and in surgical departments than non-surgical departments.Conclusions The detection rate of Enterococcus in urinary tract infection patients is quite high and varied between sexes and departments.The difference of drug resistance between species is obvious,and the bacteria species should be identified in order to use the antibiotics reasonably to postpone the development of drug resistant strains.
