Distinct difference of flaA genotypes of Legionella pneumophila between isolates from bath water and cooling tower water

ABSTRACT 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 seq...

Description
Summary:ABSTRACT 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.
