Abstract

Free-living amoebae (FLA) can accomplish their life cycle as free-living organisms; therefore it is important to know more about the distribution of FLA in the environment. The aim of the study was to determine the presence and distribution of free-living amoebae in recreational and drinking water springs. Eight springs were selected and the samples were taken on a bimonthly basis for one year. Filtration of water samples was performed and culture was done on non-nutrient agar medium with Enterobacter aerogenes bacteria. Identification of FLA was carried out taking in account the morphological characteristics of the trophozoite and cyst. Forty one of 48 (85.4%) samples tested positive for the presence of free-living amoebae and isolated amoebae belonging to 15 genera. Genera were grouping into 4 groups in according to spatial-seasonal distribution, having Naegleria and Vermamoeba the highest frequency and distribution. The study contributed to knowledge of the diversity of free-living amoebae in springs and provided interesting information about the spatial and seasonal distribution FLA in these water bodies. 

Keywords: free-living amoebae, Naegleria, Vermamoeba, springs, recreational water.
