Acanthamoeba is a microscopic, free-living ameba commonly found in the environment that can cause rare but severe illness. Acanthamoeba causes three main types of illness involving the eye (keratitis), the brain and spinal cord (Granulomatous Amebic Encephalitis), and infections that can spread from an entry point to the entire body (disseminated disease).
