Intermediate host for hydatid disease-: (A) Man, (B) Dog, (C) Cat, (D) Foxes
Answer is A. Hydatid disease is caused by Echinococcus granulosus. The worm completes its life cycle in two hosts - Definitive Host : Dog Intermediate Host : Sheep & Cattle. Man acts as an accidental intermediate host (Dead end). The larval stage of parasite is passed in intermediate hosts including man, giving rise to hydatid cyst.
