Previous investigations of sensory systems in opecoelid cercariae have focused on chaetotaxy and ultrastructure of sensory receptors. They revealed chaetotaxic patterns within family, genus, and species as well as different receptors. Chaetotaxic and ultrastructural observations have rarely been combined. We investigated the ultrastructure of cercarial sensory receptors in conjunction with chae...

Ethidium bromide and chloramphenicol (CAP) are known to impair mitochondrial nucleic acid and protein synthesizing ability . These compounds also bring about alterations in the mitochondrial ultrastructure (2-9, 11) . Correlation of ultrastructure with biochemical changes has been shown in both eukaryotic and prokaryotic cells grown in the presence of these inhibitors (1-9) . Ultrastructural ch...
