Abstract
The concentrations of Legionella pneumophila in cooling towers may vary considerably over short periods of time, producing significant fluctuations throughout the year. Despite genetic variability, in small geographical areas the same indistinguishable pulsed-field gel electrophoresis patterns may be shared among different cooling towers and persist over time.
摘要
冷却塔中嗜肺军团菌的浓度在短时间内可能会有很大变化，导致全年出现显著波动。尽管存在基因变异性，但在小地理区域内，不同冷却塔之间可能共享相同且难以区分的脉冲场凝胶电泳图谱，并且会随时间持续存在。
