Abstract:

Experimental demonstration of the life cycle in Egypt is reported and the various stages are described. The cercaria, a minute, virgulate larva, develops in sporocysts in Bithynia subdiella, penetrates the rectal wall of dragonfly nymphs Trithemis annulata, Crocothemis erythraea, Anax imperator, and A. parthenope, and encysts in adjacent tissues. Adult trematodes were recovered from the intestine of a lizard Chalcides ocellatus 22 days after being fed metacercariae in nymphal tissue. Development almost to maturity was obtained in Rana mascereniensis but mice, hamsters, and chicks could not be infected. Author
