Tapeworm
Definition:
(n.) Any one of numerous species of cestode worms belonging to Taenia and many allied genera. The body is long, flat, and composed of numerous segments or proglottids varying in shape, those toward the end of the body being much larger and longer than the anterior ones, and containing the fully developed sexual organs. The head is small, destitute of a mouth, but furnished with two or more suckers (which vary greatly in shape in different genera), and sometimes, also, with hooks for adhesion to the walls of the intestines of the animals in which they are parasitic. The larvae (see Cysticercus) live in the flesh of various creatures, and when swallowed by another animal of the right species develop into the mature tapeworm in its intestine. See Illustration in Appendix.
Example Sentences:

(6) Infection in humans or animals by the common tapeworm of dogs and cats (Dipylidium caninum) requires ingestion of the intermediate host, the dog or cat flea containing the larva (cysticercoids) of the agent.
(7) The diphyllobothriid tapeworms are primarily restricted to the northern Canada.
(8) One hundred and seven 4-quinolinehydrazones were synthesized and tested in vivo against the tapeworm Hymenolepis nana.
(9) When the oncosphere of H. nana undergoes differentiation and development into the mature tapeworm, the infected mouse first produces anti-oncosphere antibody, followed by anti-cysticercoid, anti-adult scolex and finally anti-strobila (other than scolex region) antibodies of IgG, IgM and IgA isotypes as detected by indirect immunofluorescent antibody test.
(10) Factor analysis grouped the variables considered into 5 factors: the first was associated with veterinary assistance; the second with the animal's function and the presence of whipworms, hookworms and tapeworms; the third with cohabitation, origin and presence of coccidia; the fourth with the presence of fresh meat (cooked, raw or frozen) in the diet, age and positivity for ascarids; the fifth with sex and the presence of gastroenteric conditions.
