Cysticercus bovis

Cysticercus bovis is a larval cestode that occurs in cattle and occasionally other herbivores. It preferentially infects heart and masticatory muscles, although cysts can occur in liver, lungs and lymph nodes. C. bovis causes small cysts in cattle following ingestion of feed contaminated with C. bovis eggs passed by humans. The tissue cysts are the intermediate stage of the human tapeworm (Taenia saginata). Ingested eggs hatch in the small intestine, the embryos penetrate the bowel wall and are carried via the bloodstream to muscle, where they develop into cysts.
