echinostoma cinetorchis echinostoma cinetorchis echinostoma cinetorchis is a species of human intestinal fluke, a trematode in the family echinostomatidae. echinostoma cinetorchis scientific classification kingdom: animalia phylum: platyhelminthes class: trematoda order: plagiorchiida family: echinostomatidae genus: echinostoma species: e. cinetorchis binomial name echinostoma cinetorchisando & ozaki, 1923 distribution this species occurs in korea. hosts hosts of echinostoma cinetorchis include: cipangopaludina chinensis (gray, 1834) – chinese mystery snail, an intermediate host austropeplea ollula – as a first and main intermediate host note on hippeutis (helicorbis) cantori – this species had previously been reported as first and second intermediate host, but in a subsequent study in a laboratory setting, the species was not able to be infected at all. segmentina hemispaerula as a first and second intermediate host in korea, based on laboratory work. gyraulus convexiusculus as a potential first and second intermediate host in korea, based on laboratory work. experimentally induced infection of host species that occur in korea in a laboratory setting include: from miracidia to cercaria, i.e. as a primary intermediate host: hippeutis sp. – experimentally induced infection from cercaria to metacercaria, i.e. as a second intermediate host: hippeutis sp. – experimentally induced infection radix auricularia subspecies corecna – experimentally induced infection physella acuta, listed as physa acuta – experimentally induced infection and to a very small extent, due to the mostly lethal effect of the infection, cipangopaludina sp. – experimentally induced infection
