title: Ultrastructure of the bladder tegument of Cysticercus bovis in various stages of its development.
abstract: Early developmental stages of C. bovis possess microvilli on the tegument. The differentiation of microtriches occurs at the time of scolex formation. The distal cytoplasm contains rod-shaped bodies and vesicles of various sizes. Both organelles originate from subtegumental cells. During the development of the bladder wall, three types of cells differing in their structure and organization of granular endoplasmic reticulum are present in the subtegumental layer. After formation of the scolex the cells in which the glycogen is formed sink into the region of parenchyma. The distal cytoplasm contains sensory endings of only one type, which do not penetrate on the surface of the tegument and remain under the plasmatic membrane covering the distal cytoplasm.
