the intracellular multiplication of legionella pneumophila in protozoa from hospital plumbing systems.	between october 1987 and march 1989, we tested 144 water samples obtained from the plumbing and cooling tower systems of 5 paris hospitals for the presence of legionellae and amoebae. of the samples tested for legionella, 67 out of 144 (46.5%) were positive, and 82 out of 116 tested for amoebae (70.7%) were positive. the ability of protozoa to support the multiplication of legionella was shown by incubating samples at 35.5 degrees c for 7-15 days. prior to determining the presence of legionellae ...	1991	1961979
single clonal origin of a high proportion of legionella pneumophila serogroup 1 isolates from patients and the environment in the area of paris, france, over a 10-year period.	arbitrarily primed pcr with three primers and pulsed-field gel electrophoresis were used to characterize a set of 75 clinical legionella pneumophila serogroup 1 isolates, with no apparent epidemiological link, obtained from 24 hospitals in paris, france, from 1987 to 1997. unexpectedly, 25 clinical isolates from 15 hospitals had an identical profile (termed type a) by both methods. the same profile was subsequently found in 16 of 64 randomly selected environmental l. pneumophila serogroup 1 isol ...	1999	10405416
legionella pneumophila serogroup 1 strain paris: endemic distribution throughout france.	an analysis of 691 french clinical legionella isolates showed that the endemic l. pneumophila serogroup 1 strain paris was responsible for 12.2% of all cases of legionellosis and had a specific pulsed-field gel electrophoresis pattern. we also demonstrated the presence of this endemic clone throughout europe.	2003	12843082
