Minor differences between the two isolates were found by random amplification PCR profiling which showed an additional band with one of the isolates. Analysis of 107 <jats:italic>L. pneumophila<\/jats:italic> strains isolated from the spa waters by genome macrorestriction failed to identify the infective strain, but a closely related <jats:italic>L. pneumophila<\/jats:italic> serogroup 3 strain differing from the clinical isolates by only one band was found. To determine if the clinical <jats:italic>L. pneumophila<\/jats:italic> serogroup 1 isolates was better adapted for intracellular multiplication than related serogroup 3 environmental isolates, the growth kinetics of six isolates were determined in co-culture with <jats:italic>Acanthamoeba lenticulata<\/jats:italic>. One clinical isolate failed to grow within amoeba, while the other clinical isolate yielded the highest increase in bacterial cell count per amoeba (1200 %) and the environmental isolates gave intermediate values. Genetic analysis of <jats:italic>L. pneumophila<\/jats:italic> isolates by DNA macrorestriction does not therefore appear to reflect their growth kinetics within amoeba, and is not sufficiently discriminatory to identify potentially virulent strains.<\/jats:p>","DOI":"10.1017\/s0950268801005258","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:17:11Z","timestamp":1027775831000},"page":"231-239","source":"Crossref","is-referenced-by-count":34,"title":["Different growth rates in amoeba of genotypically related environmental and clinical <i>Legionella pneumophila<\/i> strains isolated from a thermal spa"],"prefix":"10.1017","volume":"126","author":[{"given":"M.","family":"MOLMERET","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"JARRAUD","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
