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.
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.
a species of tapeworm that most commonly inhabits the tissues of pigs during its larval stage and infects the intestine of humans in its adult form. Infrequently humans serve as the intermediate hosts for this tapeworm, and larval infestation of the muscle and brain tissue may occur. Also called pork tapeworm. See also cysticercosis, tapeworm, tapeworm infection.
Taenia soliumArmed tapeworm, measly tapeworm Parasitology The pork tapeworm, contracted from undercooked or measly pork–pork infected with larval forms of T solium, which can grow 0.9-1.8 m long in the intestine Epidemiology Self-infected by ingesting eggs from own hands after scratching or wiping his/her anus; eggs hatch in GI tract; larvae migrate through tissues and encyst Clinical Larvae that migrate to the brain and encyst–formally, cysticercosis–and cause seizures and other neurologic problems
Tae·ni·a so·li·um(tē'nē-ă sōl'ē-ŭm)
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.
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

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).
adult tapeworms in dogs and jackals and the larval stage (coenurus) in rats, mice and porcupines. It is probably a subspecies of T. serialis.
adult tapeworms in foxes and coyotes, the larval stage (cysticercus) in rodents.
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.
tapeworms are in hyenas and the cysticerci in antelopes.
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.
tapeworms found in carnivores and larval forms in rodents. Possibly a synonym for T. pisiformis.
adult tapeworms in lynx and coyote, and the intermediate stage in snowshoe lagomorphs.
the adult tapeworms in the marten and the cysticercus in the vole.

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.
adult tapeworms in genets, larval stage in rodents.
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.
adults are in the intestine of foxes and the metacestodes in microtine rodents.
adult tapeworms found in lynx, larvae in rodents.
adult tapeworms are intestinal parasites of humans, and the metacestode (Cysticercus bovis) in cattle and some wild ruminants.
the adult tapeworm is found in dogs and foxes and the metacestode, Coenurus serialis, in the subcutaneous and intramuscular tissues of lagomorphs.
see T. pisiformis (above).
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.
the adult is found in the small intestine of cats and other related carnivores and the metacestode (Cysticercus fasciolaris) in the livers of rodents.
adult tapeworms found in wolverines, larvae in lungs and pleural cavity of porcupines.
