hydatid disease

hydatid disease
hydatid disease n a form of echinococcosis caused by the development of hydatids of a tapeworm of the genus Echinococcus (E. granulosus) in the tissues esp. of the liver or lungs of humans and some domestic animals (as sheep and dogs)

* * *

a condition resulting from the presence in the liver, lungs, or brain of hydatid cysts. The cysts of Echinococcus multilocularis form malignant tumours; those of E. granulosus exert pressure as they grow and thereby damage surrounding tissues. The presence of hydatids in the brain may result in blindness and epilepsy, and the rupture of any cyst can cause severe allergic reactions including fever and urticaria. Treatment may necessitate surgical removal of the cysts. Spread of hydatid disease, particularly common in sheep-raising countries, can be prevented by the deworming of dogs.

* * *

an infection, usually of the liver or lungs, caused by larval forms (hydatid cysts) of tapeworms of the genus Echinococcus, and characterized by the development of expanding cysts. This can occur in humans, cattle, sheep, pigs, horses, and occasionally other mammals. The three types are alveolar, polycystic, and unilocular hydatid disease (qq.v.). Called also hydatidosis, echinococcus d., and echinococcosis.
