Bladder Worm

one of the larval stages of the tapeworm. The bladder worm parasitizes an intermediate host, which may be any of a number of invertebrates and vertebrates. The bladder worm resembles a bladder or sac; it contains one or more fully formed everted tapeworm heads. These heads develop into adult tapeworms in the body of the final human or vertebrate animal host. The four types of bladder worms are the cysticercoid, with one head and a caudal appendage equipped with six hooks; the cysticercus, with one head but no appendage; the coenurus, with many heads; and the hydatid, which contains daughter bladders with heads. The bladder worm must be swallowed by the final host in order to develop.

guinea worm

A nematode worm (Dracunculus medinensis) that is a parasite affecting subcutaneous tissues of humans and animals, found in tropical Africa and South Asia. The worm causes infection when its larvae are drunk in unfiltered or unsanitary water. The larvae enter the body through the stomach or duodenum, migrate through internal organs, and become adults. After mating, the adult female burrows to the subcutaneous tissue, often of the leg. The worm has been eradicated in Asia. See: Medina worm See: illustration
