医院环境及临床标本中微生物种类分布与医院感染的关系研究

Survey of the relationship between pathogen strains distribution and nosocomial infection

目的了解医院环境与临床标本中微生物菌群分布情况，探讨医院环境中微生物种类及其分布与院内感染的关系。方法收集医院环境中分离的微生物培养标本以及在临床患者标本中分离出的微生物，并作菌种鉴定和菌群分布调查。结果医院环境中的微生物种类、分布与临床感染微生物种类之间存在着密切的关系（86％相同）。结论为尽量减少院内感染的发病率，应严格把好环境这一关，并制定一系列消毒管理制度，以最大限度降低院内感染的发生。

Objective To estimate the distribution of microorganism strains isolated from hospital ward circumstance and clinical specimens, and then proceed to inquire into their interrelation to nosocomial infection, providing evidence for preventing and reducing nosocomial infection. Methods Specimens were coUeeted from hospital circumstance and each clinical laboratory, and then made a bacterial identification and pathogen strains survey. Results There was a closed correlation between the microorganism strain isolated from hospital circumstance and clinical infection pathogen（86% ）. Conclusion A series of disinfection management measures should be made and formulated so as to reduce the hospital infection rate as far as possible.
