Summary
Variations in the fine structure of the tegument of Taenia hydatigena have been shown to exist between areas on the same worm, and between worms of different ages. Microtriches on worms 20 days and older could be separated into three distinct types restricted to the following regions; the ‘immature-gravid’ region, the sucker region, and the surface of the rostellum. The absence of a microthrix border and distal cytoplasm at the distal end was a characteristic of worms up to 7 days old. Electron dense structures similar to rhabdomorphus organites were prominent in the distal cytoplasm of the scolex, but were absent from the distal cytoplasm of the ‘immature-gravid’ region. Structures considered to be elements of the sensory system were identified in all regions except the surface of the rostellum enclosed by the circlet of hooks.
