| Abstract: | The tegument of larval Taenia crassiceps possesses a surface coat rich in both neutral and acidic carbohydrates. Neutral glycans were detected in Golgi vesicles of the tegument perikarya, vesicles of the distal tegument, and on the surface of the plasma membrane. Autoradiographs indicated the tegument perikarya as major sites of 3H-galactose incorporation into acid-insoluble macromolecules. The labeled material is subsequently translocated to more superficial regions of the tegument, then concentrated in the brush border. Loss of radioactivity is appreciable within 6 hr of the synthesis of this material, indicating continual replacement of this tegument surface component. |
