Ribeiroia ondatrae has an indirect complex life cycle. 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.

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 — ბრტყელი ჭიების პარაზიტისებრთა გვარი ტრემატოდების We developed an eDNA method to examine the distribution and abundance of the trematode Ribeiroia ondatrae, a pathogenic parasite known to cause malformations in North American amphibians.

A flatworm parasite called Ribeiroia ondatrae infects several species of frogs just as they're developing their limbs, causing an assortment of defects such as no legs or even multiple legs that Ribeiroia ondatrae has an indirect complex life cycle. 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. The normal percentage of frog deformation in a population is between 0-5% But in the western United States, the number of mutated frogs has increased dramatically since 1995 Habitat loss is a major factor but this parasite is posing a real threat Scientists are trying now to 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 Ribeiroia ondatrae is a parasite in the genus Ribeiroia which is believed to be responsible for many of the recent increases in amphibian limb malformations, particularly missing, malformed, and additional hind legs.

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 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. Their testes are situated at the posterior end, the Ribeiroia ondatrae has an indirect complex life cycle. 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.

In amphibians, for example, infection by the trematode Ribeiroia ondatrae causes dramatic morphological changes in host body plan, such as missing, misshapen or extra limbs –. This extreme phenotypic manipulation, which can affect >50% of emerging frogs in a population, is hypothesized to increase parasite transmission by enhancing bird and mammal predation on infected frogs [29] – [31] .
