- In medicine, taenia is a genus (group) of large tapeworms some of which are parasitic in humans. In anatomy, taenia refers to a band or a structural line and applies to several bands and lines of nervous matter in the brain. In Latin, taenia means a ribbon or tape. Taenia is also spelled tenia.
* * *A genus of cestodes that formerly included most of the tapeworms, but is now restricted to those species infecting carnivores with cysticerci found in tissues of various herbivores, rodents, and other animals of prey. SEE ALSO: tapeworm. [see t.]- T. armata SYN: T. solium.- T. crassicollis SYN: T. taeniaeformis.- T. demerariensis former name for Davainea madagascariensis.- T. dentata SYN: T. solium.- T. equina SYN: Anoplocephala perfoliata.- T. hominis unusual form of T. saginata.- T. hydatigena a tapeworm of dogs, cats, wolves, foxes, and other carnivores; the larva is known as Cysticercus tenuicollis.- T. madagascariensis former name for Davainea madagascariensis.- T. minima former name for Hymenolepis nana.- T. ovis a tapeworm of dogs and foxes whose larval form is found in the muscles of sheep; heavy larval infections in sheep can have severe economic consequences due to condemnation of carcasses at meat inspection.- T. pisiformis a common tapeworm of dogs, foxes, and other carnivores; the larval form is Cysticercus pisiformis.- T. quadrilobata SYN: Anoplocephala perfoliata.- T. saginata the beef, hookless, or unarmed tapeworm of humans, acquired by eating insufficiently cooked flesh of cattle infected with Cysticercus bovis.- T. solium the pork, armed, or solitary tapeworm of humans, acquired by eating insufficiently cooked pork infected with Cysticercus cellulosae; hatching of ova within the human intestine may result in establishment of cysticerci in human tissues, resulting in cysticercosis. SYN: T. armata, T. dentata.- T. taeniaeformis one of the common tapeworms of household cats; the larval form is called Cysticercus fasciolaris. SYN: Hydatigera taeniaeformis, T. crassicollis.

* * *n.a genus of large tapeworms, some of which are parasites of the human intestine. The 4-10 m long beef tapeworm, T. saginata, is the commonest tapeworm parasite of humans. Its larval stage (see cysticercus) develops within the muscles of cattle and other ruminants, and people become infected on eating raw or undercooked beef. T. solium, the pork tapeworm, is 2-7 m long. Its larval stage may develop not only in pigs but also in humans, in whom it may cause serious disease (see cysticercosis). See also taeniasis.
