A free living amoeba, which can be found in tap water, making contact-lens wearers particularly susceptible to infection. It has been known to cause keratitis and sometimes, in extreme cases, blindness. Curing the infection can be difficult. Prevention is better than cure.
Acanthamoeba is a genus of amoebae, one of the most common protozoa in soil, and also frequently found in fresh water and other habitats. The cells are small, usually 15 to 35 Î¼m in length and oval to triangular in shape when moving. The pseudopods form a clear hemispherical lobe at the anterior, and there are various short filose extensions from the margins of the body.
