Humans become infected by accidental ingestion of dog or cat fleas that contain D caninum cysticercoids (larva).

How long can Proglottids live?

An adult tapeworm consists of a head, neck and chain of segments called proglottids. When you have an intestinal tapeworm infection, the tapeworm head adheres to the intestinal wall, and the proglottids grow and produce eggs. Adult tapeworms can live for up to 30 years in a host.

Can I get tapeworms from Proglottids?

As the proglottid dries, it becomes a golden color and eventually breaks open, releasing the fertilized eggs into the environment. A proglottid may contain as many as 20 tapeworm eggs.

How is a person infected with a tapeworm?

Tapeworm infection is caused by ingesting food or water contaminated with tapeworm eggs or larvae. If you ingest certain tapeworm eggs, they can migrate outside your intestines and form larval cysts in body tissues and organs (invasive infection).

What are metacestodes and what is their function?

Metacestodes are fluid-filled, asexually proliferating vesicles, which are entirely covered by the laminated layer, an acellular carbohydrate-rich surface structure that protects the parasite from immunological and physiological reactions on part of the host. Marija Stojkovic,

What is the larval stage of hexacanth?

Hexacanth is the larval stage of Taenia which are released when eggs are hatched. The hexacanth then develops into cysticercus or metacestode phase in voluntary muscles. Then, what is a Hexacanth embryo?
