title: Novel Acanthamoeba 18S rRNA gene sequence type from an environmental isolate.
abstract: The free-living amoebae, Acanthamoeba, can act as opportunistic parasites on a wide range of vertebrates and are becoming a serious threat to human health due to the resistance of their cysts to harsh environmental conditions, disinfectants, some water treatment practices, and their ubiquitous distribution. Subgenus classification based on morphology is being replaced by a classification based on the sequences of the 18S rRNA gene with a total of 18 different genotypes (T1-T18). A new environmental strain of Acanthamoeba isolated from a waste water treatment plant is presented in this study as a candidate for the description of the novel genotype T19 after phylogenetic analysis.
