a larval form of tapeworm.

Cysticercus

(sis'ti-ser'kŭs),
Originally described as a genus of bladderworms, now known to be the encysted larvae of various taenioid tapeworms; the generic name is, however, retained as a convenience in referring to the larval encysted forms. See: cysticercus.
Synonym(s): bladderworm
[G. kystis, bladder, + kerkos, tail]

cys·ti·cer·cus

, pl.

cys·ti·cer·ci

(sis'ti-ser'kŭs, -ser'sī),
The larval form of certain Taenia species, typically found in muscles of mammalian intermediate hosts that serve as a prey of various predators; it consists of a fluid-filled bladder in which the invaginated cestode scolex develops.
See also: Taenia saginata, Taenia solium.

Cysticercus

/Cys·ti·cer·cus/ (-ser´kus) a former genus of larval forms of Taenia, including C. cellulo´sae, the larva of Taenia solium and C. bo´vis, the larval form of Taenia saginata.

cysticercus

The larval stage of many tapeworms. It consists of a head segment with attaching hooks or suckers (scolex) enclosed in a fluid-filled sac. Tapeworm in man is normally acquired by eating undercooked pork or beef containing cysticerci.

cysticercus

the larval form of a tapeworm which grows into the adult when eaten by the primary host, and consists of a SCOLEX inverted into a large bladder. When ingested the outer cyst wall is digested, the scolex everts and the bladder disappears. The scolex attaches to the intestinal wall of the host and a new tapeworm forms with the growth of proglottides. See Fig. 126 .

Cysticercus

larval (metacestode) stage, consisting of an invaginated scolex surrounded by a fluid-filled cyst cavity, of cyclophyllidean cestodes in the family Taeniidae. Now considered to be an invalid generic name. The common ones are listed below.

Cysticercus bovis
larval stage of taeniasaginata, a tapeworm of humans. The cysticerci are found in the muscles and other tissues of cattle. Humans are infected by eating uncooked beef. Called also beef measles.
Cysticercus cellulosae
larval stage of taeniasolium, a tapeworm of humans. The cysticerci are found in the skeletal and cardiac muscles of the pig and in the muscles and central nervous system of humans. Humans are infested by eating uncooked pork. Called also pork measles.
Cysticercus fasciolaris
the larval stage of taeniataeniaeformis, a tapeworm of cats and wild Felidae and related species. The cysticerci are in the liver of rodents.
Cysticercus ovis
the larval stage of taeniaovis, a tapeworm of dogs and wild carnivores. The cysticerci are found in the skeletal and cardiac muscles of sheep and goats. Dogs are infected by ingesting raw infected meat.
Cysticercus pisiformis
the larval stage of taeniapisiformis, a tapeworm of dogs and wild carnivores. The cysticerci are in the peritoneal cavity of rabbits and hares.
Cysticercus tarandi
the larval stage of taeniakrabbei, a cestode parasite of dogs and wild carnivores. The cysticerci are found in the muscles of wild ruminants.
Cysticercus tenuicollis
the larval stage of the tapeworm taeniahydatigena, a tapeworm of dogs and wild carnivores. The cysticerci are found in the liver and on the peritoneum in sheep but also in other ruminants including wild ones and pigs. Infection in the dog occurs when infected offal is fed raw. Called also long-necked bladderworm.
