ABSTRACT
OBJECTIVE To investigate the susceptibility of Enterococcus faecalis and E.faecium isolated from system and urinary tract infected patients and provide data for anti-infection therapy.METHODS The susceptibility(MIC) of 249 Enterococcus strains was tested by agar dilution method.RESULTS All 249 strains of Enterococcus(117 strains of E.faecalis and 132 strains of E.faecium) were isolated from urinary tract or systemic infection patients.The isolated rate of E.faecalis(68.4%) was higher than that of E.faecium(50.0%) in urinary tract isolates.Meanwhile,the isolated rate of E.faecium(50.0%) was obviously higher than that of E.faecalis(31.6%) in systemic infection isolates.The drug susceptibility rate of E.faecalis was higher than that of E.faecium to gatifloxacin,ciprofloxacin,penicillin,ampicillin and high-level gentamicin but lower for minocycline.All Enterococcus were susceptible to vancomycin,teicoplanin and linezolid.They were almost 100.0% resistant to erythromycin.The susceptibility rate of E.faecalis(39.5%)was higher than E.f aecium(15.3%) to high-level gentamicin.The susceptibility rate of E.faecalis isolated from blood was higher than the strains isolated from urinary tract to all antibiotics.E.faecium isolated form blood was almost 100% resistant to gatifloxacin,ciprofloxacin,penicillin,ampicillin and erythromycin.CONCLUSIONS The drug susceptibility of E.faecalis and E.faecium which cause systemic and urinary tract infection is different.The available therapy project should be selected based on the resistance character.At present,vancomycin,teicoplanin and linezolid are the best choice for treatment against the infection caused by Enterococcus.
