Cysticesrosis is caused by infestation of the larvae of Taenia solium to various tissues (Brain, Muscles, eye ,etc).

• Cysticercosis is caused by the larval form of Taenia solium (pork tapeworm). Taenia solium is a member of Phylum Platyhelminthes, class Cestoda, Order Cyclophyllidea and family Taeniidae. The common larval stage of Taenia solium was also known as Cysticercus cellulosae.
• T. solium worms may reach a length of several meters.
• The scolex has four suckers, and a double crown of prominent hooks, which attach to the intestinal mucosa.T. solium eggs are spherical and 30 to 40 µm in diameter.^[1]
• The cysticercus larva completes development in about 2 months. It is semi-transparent, opalescent white, and elongate oval in shape and may reach a length of 0.6 to 1.8  cm.

  Photomicrograph of a brain tissue specimen revealed the presence of cysticerci in a case of cysticercosis, an infection due to the ingestion of eggs of a pork tapeworm, Taenia solium. Infestation of the brain tissue by larval tapeworms is known as neurocysticercosis (100X mag). From Public Health Image Library (PHIL). ^[2]
