Cystic echinococcosis (CE), or hydatidosis, is a parasitic zoonosis endemic to Argentina in regions where social, cultural, and environmental conditions create an epidemiological environment that favors the life cycle of Echinococcus granulosus. In the Province of La Pampa, there are reports of high prevalence in cattle, although there are no updated studies on prevalence and the risk factors that could lead to transmission to humans, especially in western La Pampa, a region historically with a higher prevalence. A current limitation in CE diagnosis is the lack of specific diagnostic systems in dogs, due to limitations in the production of antigens and antisera. The objective of this research was to identify hydatid cysts through macroscopic diagnosis in slaughterhouses and to evaluate an alternative for the production of adult Echinococcus granulosus in an animal with facility for the production of adult parasites from the inoculation of Merions with scolices obtained from fertile hydatid cysts.
