Taenia

 [te´ne-ah]
a genus of tapeworm. See figure at tapeworm.
Taenia sagina´ta a species 4 to 8 meters long, found in the adult form in the human intestine and in the larval state in muscles and other tissues of cattle and other ruminants; human infection usually results from eating inadequately cooked beef.
Taenia so´lium a species 2 to 4 meters long, found in the adult intestine of humans; the larval form most often is found in muscle and other tissues of the pig. Human infection results from eating inadequately cooked pork.

Taenia

[tē′nē·ə]
Etymology: Gk, tainia, ribbon
a genus of large parasitic intestinal flatworms of the family Taeniidae, class Cestoda, having an armed scolex and a series of segments in a chain. Taeniae are among the most common parasites infecting humans and include T. saginata, the beef tapeworm, and T. solium, the pork tapeworm.

Taenia

Latin, taenia, ribbon, tape Parasitology A genus of large segmented, with each segment or proglottid capable of producing eggs tapeworms–cestodes-that parasitize mammalian GI tracts Epidemiology Infestation is linked to consumption of raw pork–T solium or beef–T saginata; eggs are dispersed by individual or groups of proglottids, which detach and pass out with the stool. See Taenia solium.

Taenia

(te'ne-a) [L. taenia fr Gr. tainia, tape, ribbon]
A genus of tapeworms, parasitic flatworms belonging to the class Cestoda, phylum Platyhelminthes. They are elongated ribbon-like worms consisting of a scolex, usually with suckers and perhaps hooks, and a chain of segments (proglottids). Adults live as intestinal parasites of vertebrates; larvae parasitize both vertebrates and invertebrates, which are intermediate hosts. See: taeniasis; tapeworm

Taenia asiatica

A species found in China, Southeast Asia, and Korea, structurally similar to T. saginata.

Taenia lata

See: Diphyllobothrium latum

TAENIA SAGINATA: beef tapeworm (orig. mag. ×100)

Taenia saginata

A species whose larvae live in cattle. The adult worm lives in the small intestine of humans, who acquire it by eating insufficiently cooked beef infested with the encysted larval form (cysticercus or bladderworm). Adult worms may reach a length of 15 to 20 ft (4.6 to 6.1 m) or longer.
Synonym: beef tapeworm; unarmed tapeworm See: illustration

TAENIA SOLIUM: (Orig. mag. ×5)

Taenia solium

A species whose larvae live in hogs; its scolex possesses a row of hooks about the rostellum. The adult worm lives in the small intestine of humans, who acquire it by eating insufficiently cooked pork. Adult worms may take up residence in the intestine, depriving the host of food. Larval forms of T. solium may encyst in the brain, resulting in seizures. In some underdeveloped nations the onset of seizures in adulthood is presumed to be the result of neurocysticercosis until proved otherwise. The infection is treated with niclosamide or praziquantel.
Synonym: armed tapeworm; pork tapeworm See: illustration

1. A flat band or strip of soft tissue.

taenia coli

The three bands of smooth muscle into which the longitudinal muscle layer of the colon is gathered. They are taenia mesocolica (mesenteric insertion), taenia libera (opposite mesocolic band), and taenia omentalis (at place of attachment of omentum to transverse colon).

taenia fimbriae

The folded or recurved lateral edge of the fimbria to which the epithelium covering the choroid plexus of the inferior horn of the lateral ventricle is attached.

taenia pontis

One or two small transverse bands of fiber at the rostral border of the pons.

taenia semicircularis

The stria terminalis.

taenia thalami

taenia ventriculi tertii

The taenia of the third ventricle.

Taenia

a genus of cyclophyllidean tapeworms of the family Taeniidae. The adult tapeworm inhabits the intestine of carnivores, the larval stage (metacestode) invades the tissues of a variety of animals, in some cases humans. They cause some economic loss due to condemnation of offal, but their greatest importance is their zoogenetic potential, and the preoccupation of humans with the danger of becoming infected.
Tapeworms and their hosts are listed below, but species whose intermediate hosts are unknown are: T. bubesi (lion), T. crocutae (spotted hyena), T. erythraea (black-backed jackal), T. gongamai and T. hlosei (lion and cheetah), T. lycaontis (hunting dog), T. regis (lion).
