The ultrastructure of helminth. VI. The body wall of Opisthorchis viverrini (Poirier, 1886)

Electron microscopy of the body wall of Opisthorchis viverrini shows the integument which is connected to the epidermal cell with fine protoplasmic tubules, to form a syncytium, as in Clonorchis sinensis and other trematodes. Vacuole-like secretory granules are distributed in the matrix of the integument, and mitochondria are arranged at the proximal outer surface of the integument. The crystalline inclusions are observed in the perinucleus of some epidermal cells.
