It can use multiple aquatic snail species as first intermediate host, such as Planorbis planorbis, Anisus vortex, and Radix peregra. The definitive host species include the wild duck, the tufted duck, the domestic chicken, and the brown rat.[1][3] In the definitive host it resides in the small intestine, cecum, and rectum.[3] In Thailand and Laos E. miyagawai, is more common parasite of free-living ducks than E. revolutum.[2]
Taxonomy
editGenetic analysis has shown that the species can be subdivided into two different lineages; a Eurasian lineage and an Australian lineage. The latter includes individuals from Australia and the Americas. Genetic exchange within these lineages over such long distances is possible through distribution by birds.[2] However, it has also been suggested that the Eurasian lineage might actually present a distinct species.[5]
Furthermore, Echinostoma miyagawai is a cryptic species and there is still debate about whether E. miyagawai and E. robustum should be considered as one species, or two separate species.[2][3][6] The TkD1Int5 sequence implies two individual species,[7] but the results from the mitochondrial genes cytochrome c oxidase, and NADH dehydrogenase are less clear.[2][3] This debate is further complicated by the notion that hybridisation between the two species might occur.[7]
