[Fine structure of the bladder tegument of Taenia saginata metacercaria with reference to establishment in the final host].
The ultrastructure of the bladder tegument of the metacestode of Taenia saginata, with considerations on the establishment in the definitive host. The tegument surface of invaginated Taenia saginata metacestodes was demonstrated by scanning electron micrograph. The tegument is folded irregularly and its surface is amplified by the presence of microtriches, 44-45 microtriches/micron 2. The microtriches are about 500 nm long and have an absorptive function. Likely, form and sensity of microtriches turn out a capillary attraction that plays an important role in contact with surface (finger, tongue and duodenum of man, instrumentarium , glass, plastics). This opinion is supported by scanning electron micrograph of the surface of finger-tips, of the tongue and the duodenum of man.
