Humans may serve as definite host, as intermediate host, or as both, depending on the species of tapeworm. New proglottids are produced near the anterior end, and move posteriorly as they mature. Mature, gravid proglottids detach from the strobila. Most common tapeworm found world wide. Acquired from uncooked beef.
Humans are definitive hosts.
Very common in Lebanon and Ethiopia. Occasionally found in Canadian dairy cattle herds. Eggs are released in human feces individually or still within tapeworm proglotids. Segments differentiated from pork tapeworm by having large number of uterine branches when viewed with a trans-illuminating light source. Acquired by eating uncooked pork.
