is one kind of free-living amoebae (FLA) which ubiquitous in various aquatic environments. Several Acanthamoeba
species are pathogenic and host other pathogens such as Legionella, but the presence of Acanthamoeba
and its parasites as well as the related infection risk are not well known. In this study, the surveillance and evaluation of the infection risk of Acanthamoeba
in different aquatic environments was investigated. Water samples were collected from a river, intake areas of drinking water treatment plants, and recreational hot spring complexes in Taiwan. A total of 140 water samples were tested for the presence of Acanthamoeba
spp.. In addition, phylogenetic characteristics and water quality parameters were also assessed. The pathogenic genotypes of Acanthamoeba
T4 were abundant in the hot spring water. Taken together, Acanthamoeba
contamination in recreational hot springs and drinking water source warrants more attention on potential legionellosis and amoebae infections.
