WebInside each daughter sporocyst, cercariae are produced . Cercariae migrate to the respiration chamber where they are shed in slime ball from the snail . After a slime ball is ingested by the second intermediate host (ant), the cercariae become free in the intestine and migrate to the hemocoel where they become metacercariae . http://www.ndvsu.org/images/StudyMaterials/Parasitology/General-life-cycle-of-trematodes.pdf
While the details vary with each species, the general life cycle stages are: The egg is found in the faeces, sputum, or urine of the definitive host. Depending on the species, it will either be non-embryonated (immature) or embryonated (ready to hatch). The eggs of all trematodes (except schistosomes) are operculated. Some eggs are eaten by the intermediate host (snail) or the… WebApr 1, 2002 · Within the sporocyst, a special form of asexual reproduction, known as polyembryony, then occurs. The product of this clonal type of reproduction will vary according to the species of trematode. The stage produced may be a daughter sporocyst, in which case additional polyembryony will occur; or, it may be a redia.
