The ultrastructure of the Iodamoeba bütschlii cyst from human feces was studied. The glycogen mass appears as a compact dense body in the cytoplasm without any surrounding membrane. The cytoplasm has no mitochondrion. The nucleus shows a distinct nucleolus filled with electron-dense particles. On one side of the nucleolus are electron-dense cytoplasmic masses measuring 200-400 nm. The nuclear membrane is two-layered and shows pores.
