Q. What is the life cycle of a tapeworm?

The Pregnant proglottids with taenia eggs are released together with human feces. If ingested by the intermediate hosts, bovineor swine the eggs break inside their intestines and the larva trespass the mucosa and gains the circulation to settle on heart, muscles, brain and other organs of these animals and then differentiate into cystic larvae called cysticerci. Humans happen to infected when eating raw or badly cooked swine or bovine meat contaminated by cysticerci. In a human intestines the cysticerci develop into adult worms and the cycle goes on.
