There its development proceeds through the acanthella stage toward the cystacanth stage, which is infective to the vertebrate definitive host. If the parasites encyst in the open, they will be accidentally ingested by the definitive host, usually a grazing mammal of some sort. The transmission process from the definitive host to a snail invariably involves either a miracidium or an egg. Definitive hosts for trematodes range from the rather locallyrestricted fishes to broad-ranging and mobile birds and mammals. The gammarids are orally infected when ingesting parasite eggs released in the faeces of the definitive host. Future studies using additional, more highly variable loci will provide more definitive evidence for zoonotic transmission in these and other communities. In both the intermediate host and particularly the definitive host, there is a large degree of aggregation of parasites. The metacercariae induce cataracts, and are generally assumed to increase the vulnerability of the fish to the definitive avian hosts. First, communities in intermediate hosts usually comprise much fewer species than those in definitive hosts. While a definitive analysis of this phenomenon cannot be provided here, it does not constitute evidence against the thesis that constraint ranking is not language-specific. Successful transmission of a digenean requires a setting where the definitive host can become exposed to infection.

Findings therefore require replication with community samples before definitive conclusions can be drawn. Patent infections are those that produce cercariae and thus can potentially infect definitive hosts. Finally, encysted metacercariae within the second intermediate host must be ingested by a suitable vertebrate definitive host for the parasite to become an egg-producing adult. Protective immunity may be stimulated by exposure to the parasite and may have a different significance in the definitive or intermediate host.
