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.

PARASITE (RIBEIROIA ONDATRAE) INFECTION LINKED TO was published by on 2015-04-13. 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.

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. 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 spp.
