Echinococcus granulosis

Hydatid sand (Echinococcus granulosus), saline wet preparation. Hydatid sand refers to the individual scolices and daughter cysts which bud off from the germinal epithelial layer and drop into the center of the fluid-filled cyst. When fluid is removed from a hydatid cyst and examined after centrifugation, the material seen in this slide is often visible. Several scolices are visible in this slide.
