Overview
Causes
- Larval form of Taenia solium (pork tapeworm). T. solium is a member of Phylum Platyhelminthes, class Cestoda, Order Cyclophyllidea and family Taeniidae. The common larval stage of T. solium was also known as Cysticercus cellulosae.T. solium worms may reach a length of several meters. The scolex has four suckers, and a double crown of prominent hooks, which attach to the intestinal mucosa.T. solium eggs are spherical and 30 to 40 µm in diameter.[1] The cysticercus larva completes development in about 2 months. It is semitransparent, opalescent white, and elongate oval in shape and may reach a length of 0.6 to 1.8 cm.
- Taenia saginata tapeworms are usually 4-12 m in length, but can grow to be 25 m; the adult tapeworms produce 1,000 to 2,000 proglottids/ worm and may produce up to 100,000 eggs per worm.
- Taenia asiatica tapeworms range in size from 4-8 m, produce 700 proglottids/worm and may produce 80,000 eggs per proglottid.
