Trematoda
Sign in to saveTrematoda is a class of flatworms known as trematodes, and commonly as flukes. They are obligate internal parasites with a complex life cycle requiring at least two hosts. The intermediate host, in which asexual reproduction occurs, is a mollusk, usually a snail. The definitive host, where the flukes sexually reproduce, is a vertebrate. Infection by trematodes can cause disease in all five vertebrate groups: mammals, birds, amphibians, reptiles, and fish.
AI overview
Trematodes, commonly called flukes, are parasitic flatworms that live inside animals and require a complex life cycle involving at least two hosts—typically a snail and a vertebrate like a mammal or fish. These parasites are medically and ecologically significant because they can infect all major groups of vertebrates and cause disease in humans and other animals worldwide.

Les trématodes (Trematoda) forment une classe au sein du phylum des plathelminthes. Tous les trématodes sont des vers parasites. Les classifications précédentes les scindaient en deux ordres (ou deux sous-classes), les Monogenea et les Digenea, selon que leur cycle de vie impliquait un ou deux hôtes intermédiaires (Monoxène ou hétéroxene). Cependant la taxonomie des plathelminthes est en train de subir une importante révision. Les sources modernes classent les Monogenea en tant que classe séparée au sein du phylum. Il existe deux groupes importants en pathologie humaine : Les douves hermaphrodites (ex : Clonorchose et douve du foie) Les schistosomes (ou bilharzies) dont les sexes sont séparés.

==Etymology== Trematodes are commonly referred to as flukes. This term can be traced back to the Old English name for flounder, and refers to the flattened, rhomboidal shape of the organisms. The etymology of trematode stems from the Greek word trēmatṓdēs, which means "pierced with holes", and refers to the worm's sucker, which pierces a hole in the host while the worm is attached and feeding.
