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.
