Travels throughout the body and ends up in a parenteral site (not in the intestine) Brood capsules are secondary cysts where protoscolices develop. The hydatid will get so large that they will have several million protoscolices and several quarts of fluid. Granular material (hydatid sand) are the protoscolices that have drifted to the bottom. Ex: echinococcus granulosus (b) multilocular (=alveolar) cyst (i) (ii) Cyst infiltrates the host tissue (spreads through the host tissue) (iii) most common in liver (iv) Ih with metacestode ingested by the dh (1) inside dh it exists (2) develops into adult worm. Infected by ingesting the egg stage of the parasite. Human parasitology l#9 cestodes-pseudophyllidea: pathology of adult worm living in human host, often asymptomatic, vague abdominal symptoms nausea, pain, diagnosis, eggs in feces.
