In the United States, transmission of E granulosus in the dog-sheep cycle is known to occur most frequently in several western states, including California, Arizona, New Mexico, and Utah. In the normal life cycle of Echinococcus species, adult tapeworms (3-6 mm long) inhabit the small intestine of carnivorous definitive hosts, such as dogs, coyotes, or wolves, and echinococcal cyst stages occur in herbivorous intermediate hosts, such as sheep, cattle, and goats.

The metacestode of the related Echinococcus multilocularis (the alveolar cyst) is even more dangerous, but fortunately does not occur in the UK. Echinococcosis is classified as either cystic echinococcosis or alveolar echinococcosis. Schipper HG, Laméris JS, van Delden OM, Rauws EA, Kager PA.

For instance, neither surgery nor medical therapy is generally effective for bone, especially spinal, echinococcosis. After the developing embryos localize in a specific organ or site, they transform and develop into larval echinococcal cysts in which numerous tiny tapeworm heads (called protoscolices) are produced via asexual reproduction. 50(5):718-23. Echinococcosis. Am J Trop Med Hyg. 1997 Sep 25. for: Medscape. 186(4):1198-9; author reply 1199-200.
