By comparison, a hair is 40 to 50 micrometers wide. Like other amoebas, Naegleria reproduces by cell division. When conditions aren't right, the amoebas become inactive cysts. When conditions are favorable, the cysts turn into trophozoites -- the feeding form of the amoeba.t's formal name is Naegleria fowleri.
