Also called cysticercus or cysticercus. The larvae of tapeworms such as Taenia solium (cattle tapeworm) and Taenia solium (pigs tapeworm). They are about the size of a pea. They are the result of the development and metamorphosis of the previous stage of larvae, the hookworms (also called onchosphaera), in the bodies of intermediate hosts such as cattle and pigs. When cattle or pigs ingest the eggs of these tapeworms, the hookworms escape the eggshell in the small intestine, invade the intestinal wall, and migrate to the muscles.
