• Antique engraved illustration of the tapeworm. Vintage illustration of the cestoda. Old engraved picture. Book illustration published 1907. Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). B: the head scolex) of the tapeworm, A, B, C, D, E: metamorphosis of the cestoda. The adult tapeworm has a scolex (head), a short neck, and a strobila (segmented body) formed of proglottids. Tapeworms anchor themselves to the inside of the intestine of their host using their scolex, which typically has hooks, suckers, or both. They have no mouth, but absorb nutrients directly from the host's gut. The neck continually produces proglottids, each one containing a reproductive tract mature proglottids are full of eggs, and fall off to leave the host, either passively in the feces or actively moving. All tapeworms are hermaphrodites, with each individual having both male and female reproductive organs. Humans are subject to infection by several species of tapeworms if they eat undercooked meat such as pork (Taenia solium), beef (T. saginata), and fish (Diphyllobothrium), or if they live in, or eat food prepared in, conditions of poor hygiene (Hymenolepis or Echinococcus species). The unproven concept of using tapeworms as a slimming aid has been touted since around 1900.
