由于绿脓杆菌在院内感染病因结构上的作用日益增大,因此对该菌存活力的研究具有重要意义。作者对自油布、尘埃、各种纺织品、水和手分离的临床绿脓杆菌菌株的存活力,在室温和散射光线下进行了实验性研究。油布在油布表面的绿脓杆菌,其存活时间较短。检查方法中,受染油布冲洗液滤过法优于琼脂表面印痕法。前者在2日内尚能分离出存活的细菌,而后者仅在1～2小时后这种细菌已不复存在。尘埃室内尘埃沾染的绿脓杆菌与外界干燥尘埃上的绿脓杆菌相比,前者存活时间较长(达2～3周),而后者仅能存活数
Due to the increasing role of Pseudomonas aeruginosa in the etiological structure of nosocomial infections, the study on the viability of Pseudomonas aeruginosa is of great significance. The authors conducted an experimental study of the viability of clinical P. aeruginosa strains isolated from tarpaulin, dust, various textiles, water and hands under ambient and scattered light. Pseudomonas aeruginosa surface in tarpaulin, its survival time is shorter. Inspection methods, the staining method was better than the agar surface printing method. The former was able to isolate viable bacteria within 2 days, whereas the latter was no longer present after only 1 to 2 hours. Dust indoor dust contamination of Pseudomonas aeruginosa and outside the dry dust on the Pseudomonas aeruginosa, the former survival time is longer (up to 2 to 3 weeks), while the latter can only survive
