The manifestation of a schistosomal infection varies over time as the larval form of the parasite cercariae and later adult worms and their eggs migrate through the body. [16] If eggs migrate to the brain or spinal cord, seizures, paralysis, or spinal cord inflammation are possible.
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 ...
Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels (mesenteric veins) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum, S. mekongi, S. guineensis, and S. intercalatum). Clinical symptoms are caused by the eggs.
Schistosoma is a genus of trematodes, commonly known as blood flukes.They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis, which is considered by the World Health Organization to be the second-most socioeconomically devastating parasitic disease (after malaria), with hundreds of millions infected worldwide.

The parasitic trematodes of the genus Microphallus parasitise the snail Potamopyrgus antipodarum as an intermediate host. The parasites manipulate the snail's foraging behavior to increase the chance of it being preyed upon by the parasite's definitive hosts . The infected snail forages on the upper side of rocks during the period of the day ...
Giant African land snails, an invasive species of mollusk, poses a threat to Florida residents as it can spread meningitis from a parasite it carries. Giant snails carrying parasite that causes ...
Angiostrongyliasis is transmitted through the ingestion of the third-stage (L3), infective larva of the parasite. Human angiostrongyliasis is transmitted to people who consume raw or undercooked freshwater snails (or slugs), crustacea, amphibians, planarians, reptiles or unwashed vegetables (such as lettuce or spinach) contaminated with the ...
