Taenia solium pork tapeworm
This document discusses the Taenia solium parasite, also known as the pork tapeworm. It has an adult stage that lives in the human intestine and a larval stage (cysticercus cellulose) that lives in pigs. The life cycle involves humans ingesting pork contaminated with the larval cysts, which develop into the adult tapeworm in the small intestine. Common symptoms in humans include abdominal pain, diarrhea and nausea. The larval cysts can also spread to other tissues like brain, eyes and muscles, causing neurocysticercosis with symptoms depending on the location of cysts. Diagnosis involves examination of stool samples or imaging tests, while treatment involves antiparasitic medications like albendazole
