Abstract: Free living, cosmopolitan amoebae of the genus Acanthamoeba present a serious risk to human health. As facultative human parasites, these amoebae may cause health and life-threatening diseases, such as Acanthamoeba keratitis (AK), granulomatous amoebic encephalitis (GAE) and cutaneous acanthamebiasis. AK is a severe, vision-threatening cornea infection with non-specific symptoms and course. GAE is a unique central nervous system disease, almost always leading to death. Cutaneous acanthamebiasis is most common in patients with AIDS. The pathogenesis and pathophysiology of the diseases is still incompletely understood, therefore no definitive effective therapy is currently available. Prevention is very difficult due to Acanthamoeba ubiquity and resistance. Further studies on effective solutions for the prevention and treatment of Acanthamoeba infections are needed.
