There is generally no need to treat for E.<unk> , due to the rarity of this parasite becoming infectious. In one exceptional situation, E.<unk>  was found to be infectious: in northern Europe, stool samples and electron microscopy revealed large populations of the amoeba within a group of patients with persistent diarrhea. Some types of treatments may need to be used due to large populations. Some arsenical compounds are shown to treat the trophozoite stage, like carbarsone. Other compounds used to treat large populations of E.<unk>  include diloxanide furoate, and this usually is used in antiamebic therapy.
