The ultrastructural localization of alkaline phosphatase activity in the tegument of the cysticercus of Hydatigera taeniaeformis.

Alkaline phosphatase activity of the cysticercus of Hydatigera taeniaeformis was studied by means of electron microscopy. Beta-glycerophosphate was used as the substrate. The reaction product was localized within the microtriches of the distal cytoplasm, and in the cytoplasm and processes of perinuclear cells. Activity was also demonstrated within circular and longitudinal muscle bundles and in calcareous corpuscles.
