Extract

This paper gives an account of the mature eggs and the miracidium of Paryphostomum mehrai obtained from experimentally infected white rats, which were fed with the cysts of Cercaria mehrai obtained from naturally infected as well as artificially infected snails of the species Indoplanorbis exustus. The metacercariae develop into the adults in the intestine of the host in a period of 20 days, after which the adults begin to lay their eggs, which are passed out with the faeces of the host. The molluscan phase of the life cycle involves the gradual development of the miracidium larva after its penetration into the molluscan host into a mother rediae. The mother rediae, not more than three to five in number, were observed in the preoesophageal region of the snail host. They produce large numbers of daughter rediae, which were found migrating towards the liver mass. The daughter rediae, after fixing themselves in the liver mass, undergo further development and produce large numbers of cercariae. The entire process, from the entry of the miracidium until the cercariae are matured takes about 8 weeks.
