Additional information Detection of serum antibodies to Echinococcus plays an important role in the diagnosis of hydatid disease, since infected individuals do not exhibit fecal shedding of Echinococcus eggs. The frequency of a positive result for serum antibodies may persist for years after cyst removal. Serologic crossreactivity between Echinococcus and Cysticercus may occur.

Increasing antibody values between acute and convalescent specimens is considered evidence of recent or current infection. The frequency of a positive result for serum antibodies to Echinococcus is higher in patients with active cysts in the liver than in patients with hydatid cysts in the lung or calcified cysts. Serologic crossreactivity between Echinococcus and Cysticercus may occur.
