Recently, a trematode parasite (Ribeiroia ondatrae) was identified as the probable cause of hind-limb malformations in Pacific treefrogs (Hyla regilla) from California. We exposed a second anuran species, the western toad (Bufo boreas), to specific levels of R. ondatrae infection. In a ...

Recent laboratory and field research has supported the hypothesis that infection by the helminth parasite, Ribeiroia ondatrae , is associated with deformities, particularly in the western United States. In this study, observational and experimental evidence from eastern United States (Vermont) provides ...
(English):Recent evidence suggests that infection by larvae of the trematode Ribeiroia ondatrae accounts for a significant proportion of limb malformations currently observed in amphibian populations of North America. However, the effects of R. ondatrae infection on northern leopard frogs (Rana ...

Recent evidence from field and laboratory studies has implicated infection by a digenetic trematode – Ribeiroia ondatrae – as an important cause of such deformities. Ribeiroia spp. have a complex life cycle involving planorbid snails, amphibians and water birds. Under natural conditions, ...
