title: [Symmetry of orthonectids and dicyemids].
abstract: The analysis of the general structure of orthonectids shows that free-living sexual specimens are bilaterial, while the parasitic plasmodium is anaxonic. All worm-like stages in the life cycle of dicyemids are characterized by monaxonic heteropolar symmetry, while their infusorioform is bilaterial.
