Question

Quizplus · Accepted Answer

Hydatid disease, also known as echinococcosis, is caused by the tapeworm Echinococcus granulosus. Dogs (and other canids) are the definitive hosts, meaning the parasite reaches maturity and reproduces sexually in them. Humans become infected by ingesting the eggs of E. granulosus, which can occur through direct contact with infected dogs or by consuming contaminated food or water. Once ingested, the eggs hatch in the intestine, and the larvae then penetrate the intestinal wall and enter the bloodstream, through which they can reach and form cysts in various organs. These cysts, known as hydatid cysts, can indeed contain thousands of protoscolices, which are capable of developing into new tapeworms if ingested by a definitive host, completing the lifecycle.
