Legionella longbeachae serogroup 1 and other Legionella spp. were isolated from 73% of 45 potting soils made in Australia by 13 manufacturers but were not detected in 19 potting soils made in Greece, Switzerland, and the United Kingdom examined between March 1989 and May 1990. Several Legionella species were isolated from a small number of samples of uncomposted pine sawdusts, but it is not known whether sawdust was the source of some of the legionellae found in potting soils. Legionella spp. persisted for periods ranging from 3 to 10 months in a potting soil held at temperatures between -20 and 35 degrees C. Isolates of L. longbeachae serogroup 1 from soil did not grow at 43 degrees C, a temperature which was also lethal for this species in soil. Most Legionella spp. isolated from potting and natural soils belonged to one distinct group according to analysis of ubiquinones and were serologically related to several known species in this group. A small number of potting soils contained L. pneumophila and L. micdadei.
从13家制造商在澳大利亚生产的45种盆栽土中，73%分离出了长滩军团菌血清群1和其他军团菌属细菌，但在1989年3月至1990年5月期间检测的希腊、瑞士和英国生产的19种盆栽土中未检测到。从少量未堆肥的松树锯末样本中分离出了几种军团菌属细菌，但尚不清楚锯末是否是盆栽土中发现的一些军团菌的来源。军团菌属细菌在温度介于-20至35摄氏度的盆栽土中可存活3至10个月。从土壤中分离出的长滩军团菌血清群1菌株在43摄氏度时无法生长，该温度对该菌在土壤中也是致命的。根据泛醌分析，从盆栽土和天然土壤中分离出的大多数军团菌属细菌属于一个不同的组，并且在血清学上与该组中的几个已知物种相关。少数盆栽土中含有嗜肺军团菌和米克戴德军团菌。
