Objective In this lab, students will observe different body forms in the Phylum Platyhelminthes. The ‘bladder worms’ typically affect the liver or peritoneal cavity and are caused by the larval form (metacestode) of Taenia hydatigena, the common tapeworm of the dog family. The larval intermediate of another tapeworm of canids, Echinococcus granulosus , also may form hydatid cysts, particularly in liver and lungs. Not all cases are diagnosed because these flukes can be asymptomatic, meaning, they live 25-30 years (or up to 50 years) within your liver, bile ducts or pancreatic ducts and you may never know it. They are often acquired through ingesting fresh water cress, fresh water fish that is raw, pickled, smoked or dried.
