PROSORHYNCHUS CRUCIBULUM (DIGENEA: BUCEPHALIDAE) MIRACIDIUM MORPHOLOGY AND ITS PASSIVE TRANSMISSION PATTERN.

The article discusses a research study on the Miracidium morphology and transmission pattern of Prosorhynchus Crucibulum. Collected were adult P. crucibulum worms from conger eels for observations and light microscopy (LM) to study miracidia morphology from artificially hatched eggs while those of F. hepatica were redrawn for comparing with other species. Results showed 6,760 eggs in every one of 8 P. crucibulum adult worms while those in F. hepatica were 1,459 for every one in two adult worms. Conclusions indicated the simplified morphology in the miracidium for P. crucibulum as compared with F. hepatica and a similar pattern was observed in the P. squamatus as related to the passive way of infection.
