2009-2011年北京某医院呼吸道感染患者病原谱构成分析

目的了解呼吸道感染患者的病原菌谱构成、分布、发展情况,为探讨该医院呼吸道感染致病原因,以及进一步开展医院获得性呼吸道感染的研究提供依据。方法收集某医院2009年1月-2011年1月249例呼吸道感染患者的656份标本,按照临床细菌室常规鉴定流程进行分离、培养、鉴定;收集相关患者病历信息,并加以整理和分析。结果 249例患者共检出98株病原菌,其中革兰阳性球菌30株占30.61%,以粪肠球菌为最多占9.18%;真菌27株占27.55%,以白色假丝酵母菌为最多占18.37%;革兰阴性杆菌41株占41.84%,以铜绿假单胞菌最多占12.24%;送检的标本中以鼻咽拭子、痰、血液样本为主;分离阳性的99份标本主要是痰液,占63.64%;送检患者发病时间以秋季为发病高峰,发病例数占69.0%;77例分离阳性患者的临床表现,发现同时具备咳嗽和咳痰的患者41例;发热50例;有渗出或实变的58例。结论该医院2009-2011年呼吸道感染患者的病原菌主要以革兰阴性杆菌为主,尤其以非发酵菌的比例最大,因此应加强监测以有效减少医院获得性呼吸道感染的发生。

Analysis of pathogenic isolates causing respiratory infections in patients from a hospital in Beijing 2009-2011

OBJECTIVE To isolate and identify the pathogens from respiratory infection patients in hospital and get to know the profile of these isolates,and then establish the basis for prevention and control of bacterial-infectious diseases.METHODS A total of 656 samples of 249 respiratory infection patients from the hospital from Jan 2009 to Jan 2011 were collected and the pathogens were isolated and identified according to the procedure of department of clinical laboratory.Case history of these patients were collec...
