Digenea genera

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), infecting millions worldwide.

Opisthorchis is a genus of flukes in the family Opisthorchiidae.

Leucochloridium is a genus of parasitic trematode worms in the order Diplostomida. It Is the sole genus in the family Leucochloridiidae. 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.

genus of worms

Paramphistomum is a genus of parasitic flatworms belonging to the digenetic trematodes. It includes flukes which are mostly parasitising livestock ruminants, as well as some wild mammals. They are responsible for the serious disease called paramphistomiasis, also known as amphistomosis, especially in cattle and sheep. Its symptoms include profuse diarrhoea, anaemia, lethargy, and often result in death if untreated. They are found throughout the world, and most abundantly in livestock farming regions such as Australia, Asia, Africa, Eastern Europe, and Russia.

Trichobilharzia is a genus of trematodes in the family Schistosomatidae. They are worldwide distributed parasites of anatid birds and causative agents of human cercarial dermatitis.

Echinostoma is a genus of trematodes (flukes), which can infect both humans and other animals. These intestinal flukes have a three-host life cycle with snails or other aquatic organisms as intermediate hosts, and a variety of animals, including humans, as their definitive hosts.

Holostephanus is a genus of parasitic trematodes in the family Cyathocotylidae.

Brachylaima is a genus of trematodes that can infect the gastrointestinal tract of human beings.

Echinoparyphium is a genus of trematodes. Intermediate hosts include snails, bivalves and fish. Definitive hosts are mainly birds and mammals. thumb|Cercariae of several Echinoparyphium species

Parastrigea is a genus of trematodes in the family Strigeidae.

Tylodelphys is a genus of parasitic fluke that infects the small water fish. It induces many behavioral changes on its host. Once inside a fish's eye, it can cause partial blindness and several behavioral changes to the intermediate host. Other species of flukes are able to turn into dormant cysts at certain stages of development, but Tylodelphys spp. stays active and roams free inside the fish's eye, giving it an opportunity for it to induce parasite behavior. When Tylodelphys larvae crawl around the inside of the fish's eye, it can get in between the retina and the lens. This can cause parti
