- v. Third-person singular simple present indicative form of encyst.
Sorry, no etymologies found.
In this stage it grows into a cercaria which possesses a single opening digestive tract, suckers and a tail, enabling it to leave the snail and seek out the secondary intermediate host, usually an arthropod or a fish, where it encysts, becoming a metacercaria.
This snail, common throughout the Orient, is a vector of lung flukes, a parasitic flatworm that encysts in the lungs of livestock, wildlife, and people, causing debilitation and sometimes death.
The embryo next penetrates into the body of certain snails and encysts.
It penetrates the lining membrane of the intestines and encysts in the intestinal wall.
The larva of _Strongylus vulgaris_ enters the blood vessels of the intestinal wall and finally attaches in the great mesenteric artery, where it causes aneurisms; here it transforms to an adult without sexual organs, which passes to the walls of the cecum and encysts, giving rise to small cysts or abscesses; these cysts finally discharge to the interior of the cecum, setting the worms, now mature, at liberty in the lumen of the intestines.
In other species, typically found in temporary ponds, the pre-parasitic larva hatches from an egg, and as the pond begins to dry up it encysts on plant matter.
It either dies due to lack of nourishment or uses an alternate, though less suitable, host in which it encysts but cannot feed.
