根据西方研究，军团菌广泛分布于天然淡水水域及室内供水系统。我国尚无有关专题调查资料。本文作者从山西１１个县市采集不同性质水样３６份，进行军团菌分离培养。１０份天然水样中，２份分离到嗜肺军团菌血清群５各１株，１份分离出米克戴德军团菌１株，２份分离出未能鉴定的军团菌样菌各１株，３份接种豚鼠后动物全部发病，表现符合军团茵感染，但因故未能作满意的分离培养。２６份室内管道水样军团菌分离培养无一阳性。 According to Western studies, Legionella is widely distributed in natural freshwater waters and indoor water systems. There is no relevant survey data in our country. The authors collected 36 different kinds of water samples from 11 counties and cities in Shanxi Province for isolation and cultivation of Legionella. In 10 samples of natural water, 1 isolate of Legionella pneumophila serogroup 5 was isolated from each of 2 isolates, 1 strain was isolated from Legionella pneumophila and 2 strains were isolated from Legionella pneumophila. , All the animals were infected with 3 guinea pigs after inoculation, which was in line with Legionella infection but was not satisfactorily isolated and cultured for some reason. None of 26 samples of Legionella isolates from indoor pipelines were isolated and cultured.
