What is life cycle of Echinococcus granulosus?

Echinococcus granulosus, which causes cystic echinococcosis, is a cestode whose life cycle involves dogs and other canids as definitive hosts for the intestinal tapeworm and domestic and wild ungulates as intermediate hosts for the tissue-invading metacestode, which is the larval stage of the tapeworm (Fig. 281.1).

What causes echinococcosis?

Human echinococcosis (hydatidosis, or hydatid disease) is caused by the larval stages of cestodes (tapeworms) of the genus Echinococcus. Echinococcus granulosus (sensu lato) causes cystic echinococcosis and is the form most frequently encountered. Another species, E. multilocularis, causes alveolar echinococcosis,

How long do Echinococcus granulosus infections remain asymptomatic?

Echinococcus granulosus infections often remain asymptomatic for years before the cysts grow large enough to cause symptoms in the affected organs. The rate at which symptoms appear typically depends on the location of the cyst.
