Acanthamoeba

[əkan′thəmē′bə]

a genus of free-living ameboid protozoa typically found in moist soil and water. The organisms may enter the body through a break in the skin, causing a localized infection, or even though the nose, causing systemic infections of the lung, genitourinary system, brain, and central nervous system. Disseminated cutaneous lesions caused by this organism are seen particularly in patients with AIDS. Although an infection may be fatal, cases are more commonly chronic.
