Transmission electron microscopy of sensory receptors ofEchinostoma revolutum (Froelich 1802) cercaria (Digenea: Echinostomatidae)

  • Z. Žďárská
Original Investigations


Nonciliate, uniciliate, and multiciliate receptors were shown by transmission electron microscopy to occur in the body tegument ofEchinostoma revolutum (Froelich 1802) cercariae. Detailed studies revealed three types of nonciliate, four types of uniciliate, and one type of multiciliate sensory endings. Most receptors were singly distributed. Only a few of them formed paired receptor complexes in three regions of the cercarial body. These receptor complexes were found to possess nociliate, uniciliate, and multiciliate sensory endings.
