摘要:

目的:了解肠球菌的临床分离率及其对常用抗生素的耐药性,指导临床合理使用抗生素。方法:用Vitek 2 Compact法
进行细菌鉴定及常规药敏试验。结果:临床分离到的342株肠球菌中,粪肠球菌有140例,阳性率40.9%,屎肠球菌有186例,阳
性率54.4%,其它肠球菌有16例,阳性率4.7%。342株肠球菌主要分离自尿液254例,阳性率74.3%;血液28例,阳性率8.2%;
脑脊液21例,阳性率6.1%;胆汁15例,阳性率5.3%。屎肠球菌对青霉素、氨苄西林、环丙沙星、左氧氟沙星、红霉素和四环素的
耐药率已接近或达到90%,而粪肠球菌对青霉素和氨苄西林仍保持100%敏感性。未发现肠球菌对万古霉素、利奈唑胺和替加
环素耐药。结论:革兰阳性球菌中肠球菌是引起医院感染的重要病原菌之一,肠球菌引起的感染性疾病的治疗一定要以药敏
结果为指导合理选用抗生素。

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
