Recently, a trematode parasite (Ribeiroia ondatrae) was identified as the probable cause of hind-limb malformations in Pacific treefrogs (Hyla regilla) from California. Species of digenetic trematodes, which reach a length of 1.6–3 mm and parasitize in the proventriculus of chickens, fish‐eating birds and muskrats.

Ribeiroia ondatrae has been shown to cause a variety of types of malformations in amphibians. However, little is known about the prevalence of R. ondatrae in North America. To aid in conducting field studies of Ribeiroia spp., we have developed a polymerase chain reaction (PCR)-based diagnostic.

Taxonavigation: Echinostomatoidea keywordS: Ribeiroia ondatrae, scanning electron microscopy, light microscopy, cercariae, rediae, tegument [ J pa acad Sci 86(1): 30-35, 2012 ] introduCtion Ribeiroia ondatrae (Price 1931) is a digenetic trematode of the family Psilostomidae, which occurs in lentic aquatic systems throughout North and South America (Johnson et 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. Since their widespread appearance in the mid-1990s, malformed amphibians have evoked fear, as well as fascination within the scientific and public communities. 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 trematode found in wetland habitats across much of North America (Johnson and McKenzie, 2008).

Thus this parasite acts teratogenically, e.g., up to 50% of the leopard frogs (Rana pipiens) in North America show such a disease.

Ribeiroia ondatrae is — for part of its life — an oversized head with a whip tail. In ponds, lakes and puddles, it torpedoes into tadpoles, embedding itself near where a frog’s legs will emerge. Typical of digenetic trematodes, Ribeiroia ondatrae (hereafter “Ribeiroia”) has a complex life cycle that involves snail, amphibian, and bird hosts (Johnson et al.
