Amoebae belonging to Group 2 cause the majority of reported human infections (both AK and Acanthamoeba GAE) and also constitute the majority of the strains isolated from the environment. As a complement to the morphologic classification, molecular analyses using nuclear small subunit ribosomal RNA (18S rRNA) gene sequences have divided Acanthamoeba into 17 sequence types (designated T1-T17, also called ribotypes or genotypes) (Corsaro and Venditti 2010; Gast 2001; Gast et al. Molecular and structural analysis of the 18S rRNA gene concluded that it is genetically most similar to the other Group 1 species within the Acanthamoeba genus, confirming the description of CDC:V621 as a new Acanthamoeba Group I strain.	./cache/cord-001809-azb7nie3.txt	./txt/cord-001809-azb7nie3.txt
