Taenia saginata

Taenia /Tae·nia/ (te´ne-ah) a genus of tapeworms.

Taenia echinococ´cus  Echinococcus granulosus.

Taenia sagina´ta  a species 4–8 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 1–2 meters long, found in the adult intestine; the larval form most often is found in muscle and other tissues of the pig; human infection results from eating inadequately cooked pork.

Taenia sag·i·na·ta (sj-nt)

n.

A tapeworm that is parasitic in humans and is acquired by eating infected beef that is insufficiently cooked.

Taenia saginata,

a species of tapeworm that inhabits the tissues of cattle during its larval stage and infects the intestine of humans in its adult form. T. saginata may grow to a length of between 12 and 25 feet and is the tapeworm species that most often infects humans. Also called beef tapeworm. See also tapeworm, tapeworm infection.

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).

Taenia brauni

adult tapeworms in dogs and jackals and the larval stage (coenurus) in rats, mice and porcupines. It is probably a subspecies of T. serialis.

Taenia crassiceps

adult tapeworms in foxes and coyotes, the larval stage (cysticercus) in rodents.

Taenia hydatigena

tapeworms in small intestine of dogs, wolves and wild Carnivora, and the larval stage, Cysticercus tenuicollis, found in the sheep and other ruminants, and in pigs and occasionally primates.

Taenia hyenae

tapeworms are in hyenas and the cysticerci in antelopes.

Taenia krabbei

adult tapeworms are found in the dog and in wild carnivores and the larval cestode, Cysticercus tarandi, in the muscles of wild ruminants, especially deer.

Taenia laticollis

tapeworms found in carnivores and larval forms in rodents. Possibly a synonym for T. pisiformis.

Taenia macrocystis

adult tapeworms in lynx and coyote, and the intermediate stage in snowshoe lagomorphs.

Taenia martis

the adult tapeworms in the marten and the cysticercus in the vole.

Taenia multiceps (syn. Multiceps multiceps)

the adult tapeworms are found in the dog and wild canids, the larvae, Coenurus cerebralis, in the brain and spinal cord of sheep and goat.

Taenia mustelae

adult tapeworms in martens, weasels, otters, skunks, badgers and larval stages in voles and other rodents.

Taenia omissa

adult tapeworms in the cougar and larvae in deer.

Taenia ovis

adult tapeworms are found in dogs and wild carnivores and the larval stage, Cysticercus ovis, in the skeletal and cardiac muscles of sheep and goats.

Taenia parva

adult tapeworms in genets, larval stage in rodents.

Taenia pisiformis

adult tapeworms found in small intestine of dog, fox, some wild carnivores, and very rarely in cats. The metacestode stage (Cysticercus pisiformis) found in lagomorphs, in the liver and peritoneal cavity.

Taenia polyacantha

adults are in the intestine of foxes and the metacestodes in microtine rodents.

Taenia rileyi

adult tapeworms found in lynx, larvae in rodents.

Taenia saginata

adult tapeworms are intestinal parasites of humans, and the metacestode (Cysticercus bovis) in cattle and some wild ruminants.

Taenia serialis

the adult tapeworm is found in dogs and foxes and the metacestode, Coenurus serialis, in the subcutaneous and intramuscular tissues of lagomorphs.

Taenia serrata

see T. pisiformis (above).

Taenia solium

the adults are found in the small intestine of humans and some apes, the metacestode (Cysticercus cellulosae) in the skeletal and cardiac muscle of pigs and in the brain of humans.

Taenia taeniaeformis

the adult is found in the small intestine of cats and other related carnivores and the metacestode (Cysticercus fasciolaris) in the livers of rodents.

Taenia twitchelli

adult tapeworms found in wolverines, larvae in lungs and pleural cavity of porcupines.
