Abstract

A model hot water distribution network was seeded with a virulent strain of Legionella pneumophila serotype 1. Ten weeks after inoculation, components of the system, which include aluminium discs, copper, stainless steel, silicone tubing, rubber and glass beads, were examined for colonization by L. pneumophila. The samples were stained with fluorescein-labelled antibodies to the strain and were examined with scanning electron microscopy. Colonization, which was accompanied by copious quantities of a slime-like debris, was heaviest on the rubber and least on the copper. Adherence to silicone tubing and stainless steel was observed.

摘要

在一个模拟的热水分配网络中接种了一株毒力较强的嗜肺军团菌血清1型菌株。接种10周后,对该系统的组件进行检查,这些组件包括铝盘、铜、不锈钢、硅胶管、橡胶和玻璃珠,以检测嗜肺军团菌的定殖情况。样本用针对该菌株的荧光素标记抗体进行染色,并用扫描电子显微镜进行检查。定殖现象伴随着大量黏液样碎片出现,在橡胶上最为严重,在铜上最少。观察到该菌附着在硅胶管和不锈钢上。
