Definition of Tapeworm
1. n. Any one of numerous species of cestode worms belonging to Tænia 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 larvæ (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.

Medical Definition of Tapeworm
1. The tapeworms or cestodes, are ribbon-shaped segmented worms which inhabit the intestinal tract of many vertebrates (including humans). most tapeworm infections occur in Africa, Yugoslavia, the Middle East, Southeast Asia, Mexico and parts of South America and the U.S.S.R. Some forms may be contracted (in the U.S.) from infected dogs or cats (more common in children) by ingestion of infected fleas. Taenia solium (pork tapeworm) is occasionally encountered in the United States today in immigrants or visitors from endemic areas. Taenia saginata (beef tapeworm) is seen more often, especially in those who consume raw beef. Some tapeworms have been known to live up to 20 years and exceed 10 metres in length. Often asymptomatic infestations, but unexplained weight loss, symptoms of pernicious anaemia and the presence of white eggs or ribbon-like segments of worm in stools can be seen in some. (27 Sep 1997)
