Abstract:

Over a Period of three months (summer), 108 samples of water collected from four hospitals in Te-hran. They were taken from numerous potable and non-potable water, including main supply cis-terns, calorifiers, hot and cold tap water, shower, cooling tower and drain of air condition system. Culturing of concentrated and non-concentrated water samples on Buffered Charcoal Yeast Extract (BCYE) Agar and Selective BCYE agar yielded one strain of Legionella pneumophila. It was found in cooling tower drain of one hospitals. The strain isolated belonged to sero-group 4 (Portland-1 Strain). It was also atypical being hippurate negative.

Isolation of Legionella Pneumophila Serogroups 1, 8 & 10 (Causative Agents of Legionnaires\' Disease) from Water Sources in Tehran, Iran

In this survey, 187 samples collected from 9 different sources of water in Tehran such as: water cool‌ers, neonates incubators, water bathes (37° C), little pools in parks or squares, cooling towers, hot or cold water taps, were examined for Legionnaires' disease agents. Inoculating water samples on selec‌tive and nonselective media resulted in isolation of several strains of gram negative bact...

Isolation of plasmids in Legionella pneumophila and Legionella-like organisms.

Agarose gel electrophoresis was employed to screen nine strains of Legionella-like bacteria and one strain of Legionella pneumophila for the presence of extrachromosomal deoxyribonucleic acid. Cryptic plasmids with molecular weights ranging from 46.6 x 10(6) to 59.8 x 10(6) were found in three of the isolates examined.

Draft Genome Sequences of Five Legionella pneumophila Strains Isolated from Environmental Water Samples

Legionella pneumophila is the causative agent of legionellosis. Here, we report the draft genome sequences of five L. pneumophila strains, Bnt314, Ofk308, Twr292, Ymg289, and Ymt294, isolated from environmental water samples. Comparative analyses of these genomes may reveal the survival mechanisms and virulence of L. pneumophila in the natural environment.
