The fine structure of the body wall of adult Paragonimus uterobilateralis.
The body wall of adult Paragonimus uterobilateralis was investigated by electron microscopy. The syncytial tegument contains prominent spines, mitochondria and disc-shaped granules. The apical surface forms ridges and pits, the basal membrane forms a conspicuous labyrinth. A layer of interstitial material with muscle fibres separates the syncytium from the parenchyme. The muscle fibres are organized in a transverse and a longitudinal layer and single radial fibres. Thick and thin myofilaments do not show any regular pattern. Tegumental and muscle cell bodies lie in clusters below the interstitial material. Tegumental cells are characterized by abundant ribosomes and granules, muscle cells are stacked with mitochondria. Cytoplasmic connections link both cell types to their functional portions.
