Document Summary

Characteristics of cestodes: hermaphrodites, lack a mouth and digestive system, cyton (multicellular structure interconnected multinucleus) associated with teguments, microthrix microtriches = tick worm microvilli, metacestode (juvenile), sparaganum (mature) Aquatic: pseudophyllidean (has cilia) hexacanth with a oncosphere, coracidium copepod . Non-aquatic: cyclophyllidean (no cilia) cysticercoid in beetle and cysticircus in rat hydatid cyst (major juvenile tick worm infections) Drugs for treatment: niclosamide (used to kill mollusk, tickworm, and possibly cancer therapy - csc) and praziquintal. Bump on the head with rows of hooks with suckers. Ingest eggs and eggs can go to many locations in body. Taenia saginata: found in beef and humans are only definitive host. Taeniasis is the infection of humans with the adult tapeworm of taenia saginata or taenia solium. Humans are the only definitive hosts for t. saginata and t. solium. Eggs or gravid proglottids are passed with feces; the eggs can survive for days to months in the environment.
