1. CYSTICERCOSIS PRESENTED BY- 22135 TO 22142

2. ETIOGENESIS Cysticercosis refers to tissue infection after exposure to eggs of Taenia solium , the pork tape worm. The disease is spread via the oral route through contaminated food and water, and is primarily a food borne disease.

3. T. solium can be transmitted to humans in two forms : Larval Cysts  Larval Eggs Larval cysts when ingested enter intestine and attach to abdominal wall developing into mature adult tapeworms.  Larval eggs when ingested form oncospheres and later penetrate gut wall followed by a transition to cysticercus  that enter various organ tissues.

4. PATHOGENESIS Cysticercosis is a parasitic disease caused by the larval stage of the pork tapeworm, Taenia solium . It occurs when a person ingests eggs from the feces of an infected person. These eggs hatch in the small intestine and release larvae, which migrate through the bloodstream and lodge in various tissues, most commonly the muscles, brain, eyes, and subcutaneous tissues
