Although snails infected by other Leucochloridium species are reported to continue to reproduce, [3] snails infected by L. paradoxum often show a reduction of the sexual organs. [ 6 ] The appearance and behaviour of the sporocysts is a case of aggressive mimicry , where the parasite vaguely resembles the food of the host, thereby gaining the ...
These larvae grow and take on a sac-like appearance. This stage is known as the sporocyst and it forms a central body in the snail's digestive gland that extends into a brood sac in the snail's head, muscular foot and eye-stalks. It is in the central body of the sporocyst where the parasite replicates itself, producing many tiny embryos .
Trematodiases can be transmitted through food or water that contains larval forms of the parasite. [1] [5] Infections can be transmitted through aquatic organisms which act as a host for the maturity of the parasite. [5] Foodborne trematodiasis is transmitted when organisms ingest contaminated undercooked food including aquatic plants and ...

These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
Paragonimiasis is a parasitic infection caused by the lung fluke genus, Paragonimus. It primarily affects humans (and other mammals) that consume raw or undercooked freshwater crabs, crayfish or snails infected with the parasite. [22] The transmission of paragonimiasis occurs through the ingestion of metacercariae, the infective form of the ...
Dillman said he was part of a team that made four trips to the Colorado River between March and August of 2023 to collect more than 2,000 snails of two distinct species known to transmit the worms.
