The pathology observed in a metacercarial (species not yet identified) infection of pond-raised, aquarium fish is described. In natural infections, there was extensive proliferation of cartilage resulting in loss of respiratory epithelium and occasionally in fusion of primary lamellae. Grossly, the most consistent sign of infection was flared opercula with protruding gills. Although haemorrhage was produced in early infections as the cercariae migrated, it was not macroscopically evident. A few… CONTINUE READING
