What is the difference between taeniasis and cysticercosis?

Taeniasis is the parasitic disease caused by the adult tapeworm installed within the human intestine.

Cysticercosis happens when humans ingest eggs or pregnant proglottids of taenias, for example, through badly washed food or self infection. In cysticercosis humans assume the role of intermediate hosts of the parasite and the cysticerci develop within human organs like muscles, brain, eyes and subcutaneous tissue. The brain infestation by cysticerci, a condition called as neurocysticercosis, is extremely severe and might be lead to death.
