In this paper the prevalence of Legionella in water samples from cold and warm water supply systems made of copper, iron and polyethylene was determined. Water supplied by copper pipes revealed to be nearly free of Legionella (only 2% of probes positive), but water from iron (90%) or polyethylene pipes (65% probes positive) proved to be heavily contaminated. The 82 isolates were identified as Legionella pneumophila, one from serogroup 1, the others from serogroup 4.
本文测定了铜、铁和聚乙烯材质的冷热水供应系统水样中军团菌的流行情况。铜管供应的水中几乎没有军团菌（仅2%的样本呈阳性），但铁管供应的水（90%）或聚乙烯管供应的水（65%的样本呈阳性）被证明受到严重污染。82株分离菌被鉴定为嗜肺军团菌，其中1株属于血清型1，其余属于血清型4。
