Many trematodes infect a single mollusk species as their first intermediate host, and then infect a variety of second intermediate host species. Determining the factors that shape host specificity is an important step towards understanding trematode infection dynamics.

Excystment of the Metacercariae of Echinoparyphium serratum (Trematoda: Echinostomatidae)
Journal of Helminthology, 19701. Metacercarial cysts of Echinoparyphium serratum occur in the pericardium of the snail Isidorella brazieri. Each cyst is surrounded by a nucleated, syncytial host capsule containing granules which are presumed to be melanin. The cyst wall consists of two layers and both contain acid and neutral mucopolysaccharide but little or no protein.

Excystment of Himasthla quissetensis (Trematoda: Echinostomatidae) Metacercariae In vitro
The Journal of Parasitology, 1980In vitro experiments with Himasthla quissetensis revealed that excystment involves enzy- matic weakening of the cyst wall and vigorous muscular movements of an activated metacercaria. Maxi- mum excystment occurred following 1) low pH pretreatment, 2) sodium dithionite pretreatment, and 3) a complete excystment medium containing both trypsin and bile ...

Migration and Development of Mother Sporocysts of Echinostoma caproni (Digenea: Echinostomatidae)
The Journal of Parasitology, 1997Experimental infections of the mollusc Biomphalaria pfeifferi by Echinostoma caproni miracidia (Mi) were carried out in order to analyze the migration and development of mother sporocysts (MS) at 26 C. Miracidia penetrated different parts of the host's body, such as the mantle collar, the foot and head covering (including velum and tentacles), the ...

Life history of Acanthoparyphium spinulosum Johnston, 1917 (Trematoda: Echinostomatidae).
Australian Journal of Zoology, 1960A list is given of the trematode cercariae which are commonly found in the estuarine gastropod, Pyrazus australis Quoy & Gaimard. These include: cercariae of a schistosome, Austrobilharzia terrigalensis Johnston, 1917, and of a heterophyid, Stictodora sp.; a monostomate xiphidiocercaria, probably belonging to the Microphallidae; two megalurous ...

[Development of mother sporocysts of Echinostoma caproni (Trematoda: Echinostomatidae)].
Parazitologiia, 2006New data on the migration and development of Echinostoma caproni mother sporocysts in two mollusk species of the genus Biomphalaria are obtained. It is confirmed, that the formation of primary and second generative cells takes place only as a result of undifferentiated cells' proliferation and following differentiation of some of them.
