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.
2004). 2011-08-04 · 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 2012-02-10 · The trematode Ribeiroia ondatrae could be considered the Dr. Frankenstein of the parasitic realm as many of its intermediate hosts suffer from monstrous malformations. Found prominently throughout the United States and the rest of North America, R. ondatrae infects three distinct hosts at different points in its life cycle that can include: planorbid snails, amphibians, and mammals or birds . Based on available morphological descriptions and preliminary molecular data, three species of Ribeiroia are recognized: R. ondatrae in the Americas, R. marini in the Caribbean and R. congolensis/C. lileta in Africa. 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 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.

Life Cycle: The life cycle of Ribeiroia ondatrae is indirect and utilizes three hosts. 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 cercariae swim through the water and encyst on the limb buds of tadpoles.
