<unk>  is an infection caused by the amoeba Entamoeba histolytica. Likewise<unk>  is sometimes incorrectly used to refer to infection with other amoebae, but strictly speaking it should be reserved for Entamoeba histolytica infection. Other amoebae infecting humans include: * Parasites * Dientamoeba fragilis, which causes Dientamoebiasis * Entamoeba dispar * Entamoeba hartmanni * Entamoeba coli * Entamoeba polecki * Entamoeba bangladeshi * Entamoeba moshkovskii * Endolimax nana and * Iodamoeba butschlii. Except for Dientamoeba, the parasites above are not thought to cause disease. * Free living amoebas. These species are often described as "opportunistic free-living amoebas" as human infection is not an obligate part of their life cycle. * Naegleria fowleri, which causes primary amoebic meningoencephalitis * Acanthamoeba, which causes cutaneous<unk>  and Acanthamoeba keratitis and sometimes migrates to the brain. * Balamuthia mandrillaris, which causes both skin and brain infections. * Sappinia diploidea Transmission Life-cycle of the Entamoeba histolytica<unk>  is usually transmitted by the fecal-oral route, but it can also be transmitted indirectly through contact with dirty hands or objects as well as by anal-oral contact. Infection is spread through ingestion of the cyst form of the parasite, a semi-dormant and hardy structure found in feces. Any non-encysted amoebae, or trophozoites, die quickly after leaving the body but may also be present in stool: these are rarely the source of new infections. Since<unk>  is transmitted through contaminated food and water, it is often endemic in regions of the world with limited modern sanitation systems, including México, Central America, western South America, South Asia, and western and southern Africa. Amoebic dysentery is one form of traveler's diarrhea, although most traveler's diarrhea is bacterial or viral in origin.
