Abstract:

Objective: To understand the distribution and drug resistance of commonly used antibiotics of enterococcus, in order to
provide the basis for clinical rational drug use. Methods: Vitek 2 Compact method was used for routine bacteria identification and drug
susceptibility test. Results: Among clinical isolated 342 strains of enterococcus, 140 cases were 40.9% in enterococcus, excrement
enterococcus 186 rate of 54.4%; other enterococcus 16 cases were 4.7%. 342 strains of enterococcus were mainly isolated from urine of
254 cases (74.3%), 28 cases (8.2%) and blood cerebrospinal fluid 21 cases (6.1%), 15 cases (5.3%) of bile. Excrement enterococcus to
penicillin, ampicillin, ciprofloxacin, levofloxacin, erythromycin and tetracycline resistance was close to or reached 90%, and dung
bowel aureus to penicillin and ampicillin remained 100% sensitivity. There were no resistance to enterococcus among vancomycin, rina
thiazole amine and Tigecycline. Conclusion: Enterococcus was one of the important pathogenic bacteria in hospital infection.
According to the results of drug susceptibility, clinical treatment of enterococcus infection should choose reasonable antibiotics.

Key words: enterococcus, drug sensitive test , sensitivity , resistance to drug
