医院感染542例病原菌分布的临床研究

Bacterial Distribution in Hospital Infection:A Clinical Study of 542 Cases

目的 了解医院感染致病菌分布的临床特点。方法 各种标本按细菌检验常规程序进行操作 ,细菌培养采用美国Bactec90 5 0全自动血培养仪 ,细菌鉴定采用法国生物梅里埃 ATB半自动细菌鉴定仪。结果 临床分离的致病菌为革兰阳性菌占 19%、革兰阴性菌占 4 0 %、真菌占 4 1% ,主要菌株为白色念珠菌、大肠埃希菌和肺炎克雷伯菌 ,分别占 15 7%、10 7%和 8 5 %。结论 医院感染的病原菌大多为条件致病菌 ,加强对医院感染易患因素的重点监控 。

OBJECTIVE To know the feature of bacterial distribution in hospital infection. METHODS Each sample was made according to bacterium regular examination sequence, germiculture adopts American′s Bactec9050 fully automatic blood bearing appearance, bacterium appraise adopts French ATB Expression. RESULTS Among bacteria isolated from clinical cases,19% were G +,40% were G -,41% were fungi,the most pathogens were Candida albicans, Escherichia coli and Klebsiella peneumoniae,each occupied 15 7%, 10 7% and 8 5%, respectively. CONCLUSIONS The most of the bacteria in hospital infection are the conditional bacteria. Effective methods should be seriously taken to control the hospital infection factors, and the frequency of the use of antibiotic should be reduced.
