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 ]
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 ...
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 ...
The snail excretes a juvenile form of the worm, which then has 24 hours to find a mammal host to infect or die, according to Dillman. The goal of the worm is to reach the intestines of a host ...
Eggs of different species of parasitic worm. Parasitic worms, also known as helminths, [1] are a polyphyletic group of large macroparasites; adults can generally be seen with the naked eye. Many are intestinal worms that are soil-transmitted and infect the gastrointestinal tract. Other parasitic worms such as schistosomes reside in blood vessels.
Riccardoella limacum or the white snail mite is a member of the Acari (mite) [1] family which is parasitic primarily on snails. Slug mites are very small (less than 0.5 mm in length), white, and can be seen to move very rapidly over the surface of their host, particularly under the shell rim and near the pulmonary aperture .
Another method targeting the snail host, mechanical disturbance of snail habitat, has been also tried in some areas of North America [12] and Lake Annecy in France, with promising results. Some work in Michigan suggests that administering praziquantel to hatchling waterfowl can reduce local swimmer's itch rates in humans. [ 15 ]
