Echinostoma Cinetorchis
''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 * ''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: *'' ...

Miracidia
Trematodes are parasitic flatworms of the class ''Trematoda'', specifically parasitic flukes with two suckers: one ventral and the other oral. Trematodes are covered by a tegument, that protects the organism from the environment by providing secretory and absorptive functions. The life cycle of a typical trematode begins with an egg. Some trematode eggs hatch directly in the environment (water), while others are eaten and hatched within a host, typically a mollusc. The hatchling is called a ''miracidium,'' a free-swimming, ciliated larva. Miracidia will then grow and develop within the intermediate host into a sac-like structure known as a sporocyst or into rediae, either of which may give rise to free-swimming, motile cercariae larvae. The cercariae then could either infect a vertebrate host or a second intermediate host. Adult metacercariae or mesocercariae, depending on the individual trematode's life cycle, will then infect the vertebrate host or be rejected and excreted th ...

Physella Acuta
''Physella acuta'' is a species of small, left-handed or sinistral, air-breathing freshwater snail, an aquatic gastropod mollusk in the family Physidae. Common names include European physa, tadpole snail, bladder snail, and acute bladder snail. In addition, ''Physa acuta'', ''Physa heterostropha'' (Say, 1817) and ''Physa integra'' (Haldeman, 1841) are synonyms of ''Physella acuta'' (Draparnaud, 1805). Etymology The etymology of the name ''Physella'' is obscure but could be ultimately from a Greek root. "Physella" (as a place name) is recorded in Giovanni Gemisto's printed edition of Pliny's encyclopedia, perhaps lifted from Ermolao Barbaro's ''Castigationes Plinianae'' where it is recorded as ''Physcella''. The French naturalist Jacques Draparnaud was the first to describe a species of the genus ''Physella'' and coined the name. Shell description Snails in the family Physidae have shells that are sinistral, which means that if the shell is held with the aperture facing the ob ...

Cercaria
A cercaria (plural cercariae) is the larval form of the trematode class of parasites. It develops within the germinal cells of the sporocyst or redia. A cercaria has a tapering head with large penetration glands. It may or may not have a long swimming "tail", depending on the species. The motile cercaria finds and settles in a host where it will become either an adult, or a mesocercaria, or a metacercaria, according to species.
