1980年，从加利福尼亚州长滩的一名肺炎患者身上首次分离到军团菌。13个堆肥木制品样品中的11个样品和所有11个盆栽混合物样品经阿米巴浓缩后均分离出军团菌。分别从4个样品和5个样品中分离到Long beachae。从盆栽土壤中分离到的优势军团菌是从13个样品中分离到的1号军团菌。与Long beachae不同的是，从6个样品中分离到了没有增菌的L.bozemanii。在目前的调查中，从日本盆栽土壤中分离出的大多数军团菌与人类疾病有关，这是关于公共卫生的一个重要发现。在日本，各种类型的盆栽土壤被用于园艺，如堆肥的木制品、盆栽混合物、泥炭苔藓和泥炭苔沙混合物。与澳大利亚的松树或桉树不同，日本的盆栽土壤中含有由阔叶制成的堆肥木材产品，如橡树和日本橡木(有时是柳杉和柏树)。
Legionella longbeachae was first isolated in 1980 from a patient with pneumonia in Long Beach, Calif. Legionellae were isolated from 11 of the 13 composted wood products samples and all 11 potting mix samples after amoebic enrichment. L. longbeachae was isolated from 4 and 5 samples, respectively. The most predominant species of Legionella obtained from potting soils was Legionella bozemanii serogroup 1, which was isolated from 13 samples. In contrast to L. longbeachae, L. bozemanii was isolated without enrichment from six samples. In the present survey, most of the Legionella species isolated from Japanese potting soils have been associated with disease in humans, an important finding with respect to public health. In Japan, various types of potting soils are used for gardening, such as composted wood products, potting mixes, peat moss, and peat moss-sand mixes. Japanese potting soils contain composted wood products produced from broadleaves such as oak and Japanese oak (sometimes cryptomeria and cypress), in contrast to pines or eucalyptus in Australia.
