Echinostoma cinetorchis explained

Echinostoma cinetorchis is a species of human intestinal fluke, a trematode in the family Echinostomatidae.

Distribution

This species occurs in Korea.

Hosts

Hosts of Echinostoma cinetorchis include:

• Cipangopaludina chinensis (Gray, 1834) – Chinese mystery snail, an intermediate host^[1]
• Austropeplea ollula – as a first and main intermediate host^[2]
• 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.^[3]
• Segmentina hemispaerula as a first and second intermediate host in Korea, based on laboratory work.^[3]
• Gyraulus convexiusculus as a potential first and second intermediate host in Korea, based on laboratory work.^[3]

Experimentally induced infection of host species that occur in Korea in a laboratory setting include:^[4]

From miracidia to cercaria, i.e. as a primary intermediate host:

• Hippeutis sp. – experimentally induced infection^[4]

From cercaria to metacercaria, i.e. as a second intermediate host:

• • Hippeutis sp. – experimentally induced infection^[4]
  • Radix auricularia subspecies corecna – experimentally induced infection^[4]
  • Physella acuta, listed as Physa acuta – experimentally induced infection^[4]

and to a very small extent, due to the mostly lethal effect of the infection,

• • Cipangopaludina sp. – experimentally induced infection^[4]
