Taenia solium

Cysticercosis is caused by the larval stage of Taenia solium. Humans can be an accidental intermediate host. Eggs or proglottids of the pork worm, once swallowed, hatch in the small intestine from where the larvae migrate to subcutaneous tissues, striated muscles and other tissues and vital organs (e.g. the central nervous system), where they form cysticerci. Neurocysticercosis is a severe disease.
