Taenia solium is the pork tapeworm, a tapeworm belonging to the cyclophyllid cestode family Taeniidae. These include trichinosis, "Taenia solium", cysticercosis, and brucellosis. Infection by "Taenia solium" cysticercosis, the pork tapeworm larvae in human, spares no ethnic group. When humans are infected with "Taenia solium", it causes an intestinal infection called taeniasis. He fell ill with scurvy, became infested with taenia solium and lost body hair. Among the most extensively documented was the Bladder Worm (Taenia solium). Neurocysticerosis occurs when the larvae of "Taenia solium" invade the central nervous system. The only source of "Taenia solium" infection for pigs is from humans, a definite host. Taeniasis is an infection within the intestines by adult tapeworms belonging to the genus "Taenia". It also lacks an armed scolex unlike other "Taenia". The spined loach ("Cobitis taenia") is a common freshwater fish in Europe. Unlike in other "Taenia", gravid proglottids are shed individually. "Taenia asiatica" is also usually asymptomatic. The taenia coli run the length of the large intestine. The appendages are parallel to the superficial section of the taenia coli.
