What is cysticercosis?

- Similarly to other parasitic diseases, cysticercosis is caused by the use of contaminated food or water. Sometimes autoinfection of the patient already infected with a tape worm is noted. Unlike in the brain (or eyes), in the visceral organs cysticercus is surrounded by the fibrous capsule, but remains alive for several years.
