Abstract

Primary cystic infections with Echinococcus granulosus and Taenia hydatigena were produced in laboratory animals by intraperitoneal inoculation of eggs or oncospheres. Some oncospheres which failed to become activated when treated in vitro with artificial intestinal juices retained their infectivity. Approximately 17.3% of oncospheres from 1-month-old eggs of E. granulosus produced cysts in the jird, Meriones unguiculatus. The potential value of this in vivo system for studies on the survival of taeniid eggs is discussed.
