Tape Worm (Taenia spp)

Tape worm is a long endo-parasite flat worm. It has small head called scolex with suckers and hooks by which it holds fast to the intestinal wall of its primary host, man. It belongs to the group of worm called platy-helminthes. Pig is the secondary host for Taenia solium and cattle for Taenia saginata. Tapeworm has many segments called proglotides. It has narrow neck, the narrow end of proglotides is closer to the head and it is the youngest part. The head consists of rostellum, sucker and hooks. It has no mouth, alimentary canals, arms, respiratory and blood vessels. It is a hermaphrodite which excretes through the flame cells and ducts as in other flat worms.

Life Cycle of Tape Worm

Mature proglotides with many fertilized eggs break off add pass out with faeces of the host (man).
