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 ...
Leucochloridium variae, the brown-banded broodsac, is a species of trematode whose life cycle involves the alternate parasitic infection of certain species of snail and bird. While there is no external evidence of the worm's existence within the bird host, the infection of the snail host is visible when its eye stalks become grotesquely ...
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.
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.
Schistosomiasis, also known as snail fever, bilharzia, and Katayama fever, [1] [2] [9] is a disease caused by parasitic flatworms called schistosomes. [5] It affects the urinary tract or the intestines . [ 5 ]
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.
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 .
