Description:Scolex of the parasitic pork tape worm, Taenia solium.
Pigs become infected by ingesting vegetation contaminated with T. solium eggs, or gravid tapeworm proglottids. In the animal's intestine, the oncospheres, i.e., embryos, hatch, invade the intestinal wall, and migrate to the striated muscles, where they develop into cysticerci (seen here). A cysticercus can survive for several years in the animal. Humans become infected by ingesting raw or undercooked infected meat.
