...However, even within the same order, when the plerocercoid of D. mansoni , whose definitive hosts are dogs and cats, is ingested (snakes, frogs, chickens, etc.), the larvae do not develop into adults but move around the body as larvae, causing sparganosis, which creates tumors in various places under the skin. The order Ophiopogon includes important human parasites such as the Taeniidae family's Mukou (taenia), Yukou (yukou), Tanhou (single-entry) and Tahou (multi-entry) Cestoda, as well as the Hymenopogonidae family's Dipylidium caninum and the Dipylididae family's Urizan (melon-shaped) Cestoda. Of these, in the case of the burrowing worm Taenia saginata and the burrowing worm T. solium , the oncotic larvae hatch in the intestines of the intermediate host (cattle in the former and pigs in the latter), invade the muscles and form cysts, which humans become infected by ingesting in raw meat and develop into adult worms in the intestines. *Some of the terminology that mentions "Dipylidium caninum" is listed below.
