Surface ultrastructure of a Malaysian Spirometra sp. - a preliminary study

Abstract

The external morphology of the egg, plerocercoid and adult stage of Spirometra sp. (Malaysian strain) was studied by scanning electron microscopy (SEM). The egg-shell had scattered deep pits on the surface and the pits varied in size from small to large. The microtriches on the anterior, body and posterior part of the plerocercoid stage were conoid.
