ple·ro·cer·coid

(plē'rō-ser'koyd),
A stage in the development of a tapeworm following the procercoid stage, which develops in an animal serving as the second or subsequent intermediate host; a wormlike nonsegmented larva with an invaginated scolex at one end, usually unencysted in the flesh of various fishes, reptiles, or amphibians, the ingestion of which transmits the parasite to the final host.
See also: Diphyllobothrium latum.
[G. plērēs, full, complete, + kerkos, tail]

plerocercoid

(plîr′ō-sûr′koid′)
n.
The infective larval form of certain tapeworms, having a solid wormlike body and developing from the procercoid.

plerocercoid

[plir′ōsur′koid]
the second larval stage of the cestode Diphyllobothrium latum. It develops in the second intermediate host, a freshwater fish, and is infective to humans if ingested.

plerocercoid

the second larval stage of a pseudophyllidean cestode which follows the procercoid. This larva infects a wide range of vertebrate hosts including fish, amphibia, reptiles, mammals, birds. They are elongated, have a solid body and carry an adult scolex. As a migrating larva of a tapeworm, this is an infectious stage of importance in predation; the definitive host becomes infected by eating the tissues of the second intermediate host.
