a larval form of tapeworm.

Cysticercus

(sis'ti-ser'kŭs),

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.

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 .
