Bottom Line: The study was aimed at determining whether potentially pathogenic free-living amoebae (FLA) and Legionella pneumophila can be found in lakes serving as a natural cooling system of a power plant.The bacteria were identified in the biofilm throughout the entire research period and in the subsurface water layer in July and August.Hartmanella sp. and/or Naegleria fowleri were identified in the biofilm throughout the entire research period.

ABSTRACT
The study was aimed at determining whether potentially pathogenic free-living amoebae (FLA) and Legionella pneumophila can be found in lakes serving as a natural cooling system of a power plant. Water samples were collected from five lakes forming the cooling system of the power plants Pątnów and Konin (Poland). The numbers of investigated organisms were determined with the use of a very sensitive molecular method-fluorescence in situ hybridization (FISH). The result of the present study shows that thermally altered aquatic environments provide perfect conditions for the growth of L. pneumophila and amoebae. The bacteria were identified in the biofilm throughout the entire research period and in the subsurface water layer in July and August. Hartmanella sp. and/or Naegleria fowleri were identified in the biofilm throughout the entire research period.

Fig4: Positive result of FISH hybridization for Hartmanella; bar = 50 mm

Mentions: Amoebae of the Hartmanella genus were more frequently recorded in the biofilm than in the subsurface water layer; in the former, they were identified in May, July, and October and the recorded number was always 54.4 cells cm−3 (Table 2). In the latter, they were identified only in May (54.4 cells cm−3). Hartmanella (Fig. 4) were not identified in any of the samples collected from the discharge canals.Fig. 4
