''Acanthamoeba'' keratitis is a rare disease in which amoebae invade the cornea of the eye. It may result in permanent visual impairment or blindness.〔 〕 ==Life Cycle== Species within the genus Acanthamoeba are generally free-living trophozoites. These trophozoites are relatively ubiquitous and can live in, but are not restricted to, tap water, freshwater lakes/rivers and soil. 〔(【引用サイトリンク】url=http://cdc.gov )〕 Besides the trophozoite stage, a cyst stage may also be present. Both of these stages are usually uninucleated and reproduce by the means of binary fission. When the environment poses conditions that are not favorable, the trophozoites encyst to produce double-walled cysts. 〔(【引用サイトリンク】url=http://www.dpd.cdc.gov/dpdx/HTML/FreeLivingAmebic.htm )〕 A picture reference of the life cycle may be viewed (here ).
