Tae·ni·a o·'vis

a tapeworm of dogs and foxes the larval form of which 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.

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

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 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.
