Introduction
This class differs from the Trematodes in that they have a tape-like body, with no alimentary canal. A cestode (tapeworm) is a chain (strobila) of progressively maturing, independent reproductive units (segments or proglottids) anchored at one end to the intestinal wall by a hold-fast organ (scolex). Each segment contains one set, or sometimes two sets, of male and female reproductive organs.
Tapeworm superfamilies:
- Occlusion of pancreatic ducts sometimes happens Pancreas - parasitic
- Mesocestoides in carnivores causing pyogranulomatous peritonitis
- Echinococcus granulosus in hydatid disease of lungs
