Extract

Echinococcus granulosus cysts were cultured in vitro from the oncosphere, and cyst morphogenesis is described. Cysts grew to a mean diameter of 16 mm in 120 days, with a maximum of 20 mm. An amorphous layer was apparent around the larvae during early post-oncospheral re-organization. Organisms became vesicular at 6 days and laminations appeared in the amorphous layer at 10 days. Confluence of proliferating cells to form the syncytium of the germinal membrane was observed.
