To investigate the genetic difference of Legionella pneumophila in human-made environments, we collected isolates of L. pneumophila from bath water (n = 167) and cooling tower water (n = 128) primarily in the Kanto region in 2001 and 2005. The environmental isolates were serogrouped and sequenced for a target region of flaA. A total of 14 types of flaA genotypes were found: 10 from cooling tower water and nine from bath water. The flaA genotypes of isolates from cooling tower water were quite different from those of bath water.
为了研究嗜肺军团菌在人造环境中的基因差异，我们于2001年和2005年主要在关东地区收集了来自洗浴用水（n = 167）和冷却塔水（n = 128）中的嗜肺军团菌分离株。对环境分离株进行血清分型，并对flaA的目标区域进行测序。共发现14种flaA基因型：10种来自冷却塔水，9种来自洗浴用水。冷却塔水分离株的flaA基因型与洗浴用水的flaA基因型有很大不同。
