Abstract :
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 bacteria. Among them, seven strains of Legionella pneumophilla which did not grow on
any of the above media, were identified by indirect fluorescent antibody technique (IFA) and
biochemical tests. Following confirmation by "Center National De Reference Des Legionelloses,
Faculte of Medicine Alexis Carrel, Lyon", the Center identified Legionella pneumophila of
serogroups of 1, 8 and 10. Out of 6 hospitals, 5 showed contaminated water having pneumonic
Legionellosis agents.
