T. solium consist of six stages in its life cycle. The six stages are egg, oncosphere, cysticercus, adult tapeworm, postoncospheral form and the preadult tapeworm. The preadult and the adult stage can only happen when a human consumes pork. It can be infected by the cysticercus stage because one must mature in the human’s intestine. The eggs are also shed through the human’s feces and then disbursed by a pig. This usually happens when a human eats pork that’s undercooked and also infested by cysticercus.
