Capacity building for surveillance and control of Taenia solium/cysticercosis

摘要

The terms cysticercosis and taeniasis refer to food-borne zoonotic infections with larval and adult tapeworms, respectively. The important features of these zoonoses are that the larvae are meatborne (generally beef or pork) and the adult stage develops only in the intestine of the human host (obligate). Taenia saginata (the beef tapeworm), I saginata asiatica (Taiwan Taenia) and T. solium (the pork tapeworm) are the most important causes of taeniasis in humans. Cysticercosis is a tissue infection with the larval cysticercus or metacestode stage, and occurs most commonly in pigs and cattle; Taenia saginata occurs only in beef, T. saginata asiatica in pig organs, and T, solium primarily in pork. Humans acquire the adult stage through eating improperly cooked infected meat.
