医院感染病原菌分析

目的探讨医院感染病原菌的细菌谱与药敏特点. 方法回顾性分析 218份医院感染病例中的细菌培养与药敏. 结果病原菌以致病性大肠埃希菌、弗氏志贺菌、表皮葡萄球菌所占比重最大(29.9%、19.6%、14.3%),敏感率最高的前3位抗生素为阿米卡星、庆大霉素及亚胺培南;表皮葡萄球菌、柠檬酸杆菌、阴沟肠杆菌对常用抗生素普遍耐药. 结论医院感染病原菌主要系条件致病菌,细菌培养与药敏试验既有利于早期诊断、合理应用抗生素,对于降低耐药菌株的产生也有积极意义.

Pathogenic Bacteria of Hospital Infection

OBJECTIVE To probe into the spectrum and drug sensitivity of pathogenic bacteria in hospital infection. METHODS Retrospective analysis of bacterial culture and drug sensitivity was conducted in 218 cases with hospital infection. RESULTS The proportion of Escherichia coli, Shigella flexneri and Staphylococcus epidermidis was predominant (29.9%, 19.6%, and 14.3%). The top three medicines that the sensitive rate was supreme were amikacin, gentamicin and imipenem. All of the S.epidermidis, Citrobacter and Enterobacter cloacae were resistant to the common antibiotics. CONCLUSIONS Opportunistic pathogens are the main bacteria of hospital infection. Both of the bacterial culture and drug sensitivity tests are useful not only to the early diagnosis and the use of antibiotic,but also to the reduction of the drug resistance.
