Cestodes reside in the intestine of the definitive vertebrate host and the larvae stage(s) are found in the bodies of the intermediate host(s), which can be both invertebrates and/or vertebrates. Cestodes mainly cause gastrointestinal problems, but can migrate into the brain and liver (Siles-Lucas and Hemphill, 2002).

What habitat do tapeworms live in?

The pork tapeworm has several different habitats depending on the stage in its life cycle. The preadult tapeworm and adult tapeworm can be found in the small intestine of a human host. The proglottid segments full of eggs are found in the host feces, and in the external environment where the feces are released.

What are the common host of Cestodes?

Echinococcus eggs from dog or fox fur cause human hydatid disease (humans are the intermediate host; canids are the definitive hosts). Reinfection with adult tapeworms is common; second infections with larvae are rare.
