After several Brazilian researchers, the author examines the capacity of two species of rodents Cricetidae, Holochilus brasiliensis and Nectomys squamipes, to maintain the biological cycle of Schistosoma mansoni in the field and to be parasite reservoir: (a) the role they are able to play in human endemy; (b) the methods necessary to characterize the population of Schistosoma mansoni related either to man, either to rodents, either to both.
The snail natural host is unknown.The chaetotaxy of the cercaria differs from that of other European species of Paramphis tomum and particularly from P. leydeni and P. daubneyi both species which occur in Vendée. The morphology of the adult precludes any relationship with P. ichikawai also present in Vendée. Therefore it very likely represents a species which was synonymised with P. cervi or a new species.Key-words: Paramphistomum. Cercaria. Chaetotaxy.Le cycle biologique de ce parasite a été réalisé par Postal (1984), puis Postal et Picot (sous presse) à partir des miracidiums obtenus par éclosion des oeufs d'un adulte recueilli dans la panse d'un Bovin ( Bos taurus) abattu dans l'Ouest de la France, en Vendée, à Challans. L 'adulte qui a fourni les oeufs a été déterminé Param phistom um cervi par le Professeur Sey. Des A nisus rotundatus (Poiret, 1801) originaires du Marais Vendéen ont été chacun mis en présence de 2 à 4 miracidiums. Les Mollusques, testés pendant deux mois, une fois par semaine, s'étaient révélés
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
