title: Ultrastructure of the tegument of the anoplocephalid cestode Mosgovoyia ctenoides (Railliet, 1890) Beveridge, 1978.
abstract: The tegument of the mature proglottids of M. ctenoides was examined by means of TEM. The tegument of this species consists of two layers: (1) the external cytoplasm, and (2) the tegumental perikarya situated in the cortical parenchyma. The tegument surface is covered by typical microtriches. The anucleated external layer of cytoplasm is rich in vesicles of different shape and electron-density, but it lacks mitochondria. Large pore canals penetrate the external cytoplasmic layer. This layer is separated from the perikarya by a basal lamina, being connected with the tegument cell bodies by cytoplasmic bridges. The granular cytoplasm of perikarya contains typical cell organelles such as mitochondria, GER, Golgi complexes, free rybosomes, numerous vesicles and lipid droplets inclusions. The large nuclei of the perikarya with prominent nucleoli frequently contain large intranuclear, highly osmiophilic lipid droplets.
