[Data on the life cycle of Ribeiroia marini guadeloupensis n. ssp., a trematode sterilizing Biomphalaria glabrata in Guadeloupe].

Data on the life cycle of Ribeiroia marini guadeloupensis n.ssp., Trematode sterilizing Biomphalaria glabrata in Guadeloupe. Maintenance of the life cycle with a view to an eventual control of the populations of Molluscs. In Guadeloupe (French West Indies), the definitive hosts of Ribeiroia marini guadeloupensis n.ssp. are the two species of rats: Rattus rattus and R. norvegicus. The first intermediate host is Biomphalaria glabrata, the vector of intestinal schistosomiasis. The second intermediate host is a fish (Tilapia mossambica, Poecilia reticulata). The different stages of the life cycle are described; the transmission is studied experimentally and in natural conditions. A method for producing eggs of this Trematode in large quantities is described.
