Scanning electron microscopy of Trichuris trichiura (Nematoda).
Trichuris trichiura was examined in the scanning electron microscope and revealed a double row of sucker-like structures at the anterior part. It is postulated that they may support the attachment of the worm in host tissues. The sheath of the spicule is covered with spikes and the vulval opening is surrounded by an elevated rim-like structure with indentations.
