… The order Taenia includes important human parasites such as Taenia saginata, Taenia yukota, Taenia tanhota, and Tahouta multi-enveloped worms of the Taeniidae family, as well as Taenia trichogamata, Taenia saginata, and Taenia solium of the Dipylididae family. Of these, the Taenia saginata and Taenia solium produce hooked larvae that hatch in the intestines of intermediate hosts (cattle in the former and pigs in the latter), which then invade the muscles and form cysts . Humans become infected by ingesting these in raw meat and develop into adult worms in the intestines. In addition, if the gravid proglottid of the hookworm is damaged inside the human intestine and many eggs are released, the oncocysts can cause self-infection, and the human can act as an intermediate host, with the oncocysts forming in the muscles, brain, eyes, heart, etc., causing human hookworm disease. *Some of the terminology that mentions "Taenia saginata" is listed below.
