title: [Ultrastructure of the cercomere of the cysticercoid, Trichocephaloides megalocephala].
abstract: The cercomere of the larvae of Trichocephaloides megalocephala is formed exclusively by tegumentary tissues. The cytons of the tegument contain a great number of ribosomes, developed Golgi complex and numerous mitochondria that is indicative of the intensive synthesis, protein substances first of all. A distinct secretion of multivesicular membranes into subtegumentary space and further secretion of vesicles through the distal portion of the tegument into the external cyst cavity was observed. The main function of the cercomere is a production of the ground substance which apparently fulfils a protective function as it is suggested for glycocalix.
