ABSTRACT:
Objective. The aim of this study was to determine the prevalence of [i]L. pneumophila[/i] in water supply systems, hospitals and public buildings in the Lublin region of eastern Poland. Material and methods. The study was carried out in 26 different objects in the Lublin region. The number of [i]Legionella[/i] bacteria in water samples was determined by the membrane filtration method and/or by surface inoculation in accordance with the standards. Results. The study showed the presence of[i] L. pneumophila[/i] in 166 hot water samples (74.77%). In 34.33% (n=57) of water samples the count of tested bacteria exceeded the acceptable level of >100 CFU/100 ml. Of the samples where an acceptable level of bacteria was exceeded, 49 samples had an average level of [i]L. pneumophila[/i] (100–1,000 CFU/100 ml), and the level in 8 samples was high (>1,000 CFU/100 ml). Conclusions. The water samples collected form the hot water supply system of hospitals and public buildings showed exceeded counts of[i] L. pneumophila[/i], indicating the risk of infection. The constant monitoring of water distribution systems is an important element of the control of infections caused by these organisms.
