Abstract: The ultrastructure of Cysticercus cellulosae was obscrved by transmission and scan-ning electron microscopy. The result showed that the rostellum was disc-like- There was a semispherical projection at the middle of basal lamella. Few rostellar hooks were seen on the rostellum. Round nerve papillae were seen in the base of sucker. Clubbed micro-triches and fingershaped microtriches were found abundant on thc head and neck of Cysticercus cellulosae, but few on dorsal part of the body.Flame cells were elliptic, within which nucleus, nucleolus and chromosomes were on one side and a bundle of cilia were on the other, with fibrous membranc enclosing on the distant end. Each cilium had a typical"9+2" composition. Collecting tubes were divided into smaller tubules, which gather together to form plexus. The calcareous bodies appeared as round granules and did not fuse together. The rostellar hooks were seen embedded in the parenchyma tissue of the head region.
