Taenia
Taenia is a genus of tapeworm that includes some important parasites of livestock. All members of this genus have an "armed" scolex, meaning that there are hooks on the "head" region. Proglottids have central ovary, with a vitellarium (yolk gland) posterior to it. As in all cyclophyllid cestodes, the genital pore on the side of the proglottid. Eggs released when proglottid deteriorates, and so a uterine pore is unnecessary. Important species include: Taenia saginata, which is also known as the beef tapeworm, though it can infect humans. One woman had an 81-foot-long worm in her intestine.Taenia solium, which is also known as the pork tapeworm. Taenia pisiformis, which is common in wild dogs and in rabbits, who serve as intermediate hosts.
