The life cycle of T solium revolves around its 2 developmental forms: the adult segmented worm causes taeniasis, an intestinal tapeworm infection, while the larval stage causes cysticercosis, an invasive form of infection. Pigs ingest T solium eggs. However, humans are the only host of both forms of the parasite, and pigs serve only as intermediates by harboring the cysticerci. In the intestine, the eggs release embryos, which penetrate the intestinal mucosa, enter the bloodstream, and burrow into tissues where they mature into cysticerci (infective larvae). Humans, as the definitive host, ingest the cysticerci in undercooked pork. The cysticerci mature into adult worms in the small intestine, where they attach and produce eggs (taeniasis) to continue the parasite life cycle. Cysticercosis occurs when humans act as the intermediate host. In such instances, humans ingest T solium eggs through fecal-oral contact with humans with taeniasis. The eggs hatch in the human intestine, liberating embryos that then penetrate the intestinal mucosa and disseminate to various organs (eg, brain, eye, muscle) via the bloodstream. The clinical manifestations of cysticercosis reflect the location of these cysticerci.
