The incidence and density of Legionella spp. in raw water, water at various stages of treatment, and in potable distribution water were determined by direct immunofluorescence. The number of cells reacting with Legionella-specific fluorescent antibody conjugates in raw waters ranged from about 10(4) to 10(5) cells/liter, whereas the concentrations of fluorescent antibody-positive cells in the distribution waters were generally 10- to 100-fold lower than in the raw source waters. No viable or virulent Legionella strains were isolated from either the source or distribution waters. However, Legionella spp. are infrequently isolated from water at temperatures below 15 degrees C as was the case in the system surveyed in this study.
通过直接免疫荧光法测定了原水、不同处理阶段的水以及饮用水分配系统中的军团菌属的发生率和密度。原水中与军团菌特异性荧光抗体结合物发生反应的细胞数量范围约为每升10⁴至10⁵个细胞，而分配水中荧光抗体阳性细胞的浓度通常比原水源水低10至100倍。无论是水源水还是分配水均未分离出有活力或有毒力的军团菌菌株。然而，正如本研究中所调查的系统那样，在温度低于15摄氏度的水中很少分离到军团菌属。
