Entamoeba moskovskii is a species of parasitic amoeba found in the human gastrointestinal tract. It was first described by the Soviet parasitologist A.A. Yushchuk in 1970. E. moskovskii is similar in appearance and behavior to other species of Entamoeba, but is distinct genetically and shows some differences in its life cycle. While it is generally considered non-pathogenic to humans, some studies have suggested that it may be associated with intestinal disease in certain cases. E. moskovskii is most commonly found in developing countries with poor sanitation, but has also been detected in industrialized nations.
