Abstract: Recent evidence suggests that infection by larvae of the trematode Ribeiroia ondatrae accounts for a signifi-cant proportion of limb malformations currently observed in amphibian populations of North America. However, the ef-fects of R. ondatrae infection on northern leopard frogs (Rana pipiens), one of the species most frequently reported Trematodes in the genus Ribeiroia have an indirect life cycle involving planorbid snails as first intermediate hosts, fishes or amphibians as second intermediate hosts and birds or mammals as definitive hosts. Although rarely pathogenic in definitive hosts, Ribeiroia infection can cause severe pathology and mortality in snails and amphibians. Recent evidence from field and laboratory studies has implicated infection by a digenetic trematode--Ribeiroia ondatrae--as an important cause of such deformities.

Ribeiroia ondatrae is a multi-host parasitic trematode linked to amphibian limb transformations that negatively influence the survival of affected animals. 105, 106 The first intermediate hosts

105, 106 The first intermediate hosts Parazita (Ribeiroia ondatrae) által indukált végtag-rendellenesség Pseudacris regilla békánál A Ribeiroia ondatrae a Ribeiroia nemzetségbe tartozó parazita faj, mely vélhetően a kétéltűek végtag-rendellenességeiért felelős, különösen a hiányzó, torz vagy számon felüli lábakért. We investigated interactions between the virulent trematode Ribeiroia ondatrae, which has been linked to amphibian malformations across the United States, and its amphibian host (Pseudacris regilla) using a hierarchical approach involving multi‐year regional field surveys, replicated pond enclosures, and an unreplicated ecosystem manipulation of parasite infection.

Widespread reports of malformed amphibians in North America have prompted investigations into the cause(s) and implications of the phenomenon. Recently, a trematode parasite (Ribeiroia ondatrae) was identified as the probable cause of hind-limb malformations in Pacific treefrogs (Hyla regilla) from California.
