The life cycle of trematodes is complex with both free-living and parasitic stages and involves several hosts (Fig. 4.5.1 A, B). Adults produce eggs that pass in the faeces of the host to the environment where they hatch to release a free-living larva, the miracidium. The miracidium penetrates a molluscan first intermediate host (some marine species infect annelids). After penetration the miracidium develops into a mother sporocyst, the first intramolluscan generation. It multiplies parthenogenetically, producing the second intramolluscan generation – multiple daughter sporocysts or multiple rediae. Daughter sporocysts and rediae reproduce parthenogenetically generating the larvae of the sexual adult – cercariae. There are several ways for cercariae to infect the invertebrate or vertebrate second intermediate host, which host metacercariae.
