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 spp. have a complex life cycle involving planorbid

2021. The Animal Diversity Web (online). 23 Nov 2012 A common, period-sized flatworm, Ribeiroia ondatrae, plays a key role in making frogs grow extra or misshapen limbs and skin flaps between 26 Apr 2012 Spidey, the Pacific chorus frog (Pseudacris regilla) that has extra hind limbs due to infection with a trematode parasite (Ribeiroia ondatrae, left). 5 aug. 2020 — Mikroskopbild på parasiten Ribeiroia ondatrae som infekterar amfibier.

The miracidia develop into rediae which eventually produce cercariae. The cercariae swim through the water and encyst on the limb buds of tadpoles. Ribeiroia is a genus of parasites in the class Trematoda, phylum Platyhelminthes. Currently three species and one subspecies of Ribeiroia are recognized: R. ondatrae in North America, R. marini in the Caribbean, R. m.

The first intermediate host is a Helisoma snail, which is infected by miracidia that hatch from eggs. The miracidia develop into rediae which eventually produce cercariae.

The adult worms live inside predatory birds or mammals (the definitive hosts), wherein they reproduce sexually if other worms are present. Mature adults release eggs into the host’s intestinal tract, which are passed with the feces of the host, and to develop need to end up in water. parasite (ribeiroia ondatrae) infection linked to amphibian malformations in the western united states Pieter T.

Johnson, Kevin B. Lunde, Ryan W. Haight, Jay Bowerman, and Andrew R. Blaustein Abstract: Widespread reports of malformed amphibians in North America have prompted investigations into the cause(s) and implications of the phenomenon. 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 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.
