Schistosomiasis is spread by contact with fresh water contaminated with parasites. [5] These parasites are released from infected freshwater snails. [5] The disease is especially common among children in underdeveloped and developing countries because they are more likely to play in contaminated water. [5]
Schistosoma mekongi infections are caused by the penetration of the skin by the cercariae stage of the parasite. Eggs are released into the water in urine or fecal matter. These eggs hatch and release miracidia, which penetrate and infect the intermediate host, the snail Neotricula aperta. Sporocysts are then released in the water by either ...
Leucochloridium paradoxum, the green-banded broodsac, is a parasitic flatworm (or helminth). Its intermediate hosts are land snails, usually of the genus Succinea. The pulsating, green broodsacs fill the eye stalks of the snail, thereby attracting predation by birds, the primary host. These broodsacs visually imitate caterpillars, a prey of ...
Dillman said the parasite needs snails, freshwater and a mammal to host it. First, a mammal host sheds parasite eggs in its poop, according to the Los Angeles County Department of Public Health.

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 ...
Humans can become infected with Echinostoma by eating infected raw or undercooked food, particularly fish, clams and snails. [3] Infection with these parasites tends to be common in regions where cultural dishes require the use of raw or undercooked food that may be infected with Echinostoma. [19] A mild infection may not have any symptoms. [20]
Leucochloridium is a genus of parasitic trematode worms in the order Diplostomida.It Is the sole genus in the family Leucochloridiidae. [2] Members of this genus cause pulsating swellings in the eye-stalks of snails (a phenomenon colloquially called a zombie snail), so as to attract the attention of predatory birds required in the parasites' lifecycle.
