A survey of seropositivity to antigen B, an immunodiagnostic antigen for human cystic echinococcosis, in domestic animals in Mongolia.

Cystic echinococcosis (CE) is well known to be an important zoonotic disease and national disease due to the traditional nomadic life style in Mongolia. The present study was carried out to obtain data on the seropositivity to antigen B, in domestic livestock, goats, sheep and cattle, in each province of Mongolia. The seropositivity to antigen B varied by province and ranged from 0% to 25.0% in goats, 0% to 12.5% in sheep, and 0% to 13.3% in cattle. In total, 9.2% of goats, 3.6% of sheep and 5.9% of cattle in Mongolia showed seropositivity.
