Echinococcus granulosus (dog tapeworm) is the causative agent.
Infectious agent
Hydatid disease in humans is produced by cysts that are the larval stages of the tapeworm Echinococcus. Brood capsules are formed within cysts,cysts containing 30–40 protoscoleces. Each of these is capable of developing into a single tapeworm. Symptoms depend on the location of the cyst within the body and develop as a result of pressure, leakage or rupture. The most common site for the cysts is the liver. Less commonly brain, lungs and kidneys are affected. The heart, thyroid and bone are uncommonly affected.

The incubation period varies from months to years.
Incubation period
The domestic dog and other canids, definitive hosts for echinococcus granulosus, may harbour thousands of adult tapeworms without being symptomatic.
Felines and most other carnivores are normally not suitable hosts for the parasite.
