目的为了解铜绿假单胞菌医院感染的流行病学。方法用血清型和抗菌谱联合分型方法，对患者分离株和环境分离株从检出时间、地点或部位进行动态分析。结果２１２３份样本共检出铜绿假单胞菌１７６株，分离率为０．８％～５７．１％；患者之间、患者与环境及医护人员间检出的铜绿假单胞菌未见有关联。结论铜绿假单胞菌广泛存在于呼吸病房的患者及环境中；铜绿假单胞菌医院感染，外源性因素不是主要的，飞沫、空气不是ＰＡ院内肺炎传播途径。
Objective To understand the epidemiology of Pseudomonas aeruginosa nosocomial infection. Methods Serum and antibacterial spectrum combined with typing method, the patient isolates and environmental isolates from the detection time, place or location of dynamic analysis. Results A total of 176 strains of Pseudomonas aeruginosa were detected in 2123 samples with a separation rate of 0.8% -57.1%. There was no Pseudomonas aeruginosa detected among patients, patients and the environment and health care workers Associated. Conclusion Pseudomonas aeruginosa is widely found in patients and environment of respiratory ward; Pseudomonas aeruginosa nosocomial infection, exogenous factors are not the main, droplets, air is not the PA hospital path of pneumonia.
