Flatworms
The flatworms, flat worms, Platyhelminthes, or platyhelminths (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates (having no body cavity), and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion (intake of nutrients) and egestion (removal of undigested wastes); as a result, the food cannot be processed continuously. In traditional medicinal texts, Platyhelminthes are divided into Turbellaria, which are mostly non-parasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea; however, since the turbellarians have since been proven not to be mono ...

Dicrocoeliasis
''Dicrocoelium dendriticum'', the lancet liver fluke, is a parasite fluke that tends to live in cattle or other grazing mammals. History of discovery Much of what is presently known about ''Dicrocoelium dendriticum'' is the result of the work of the naturalist Wendell Krull. While ''D. dendriticum'' was discovered by Rudolphi in 1819 and ''D. hospes'' was discovered by Loos in 1899, the full life cycle was not known until Krull and C.R. Mapes published a series of papers from 1951-1953 detailing their observations and experiments. It was known that ''D. dendriticum'' affected sheep, but everything else was a mystery. The first link in the chain was the discovery of the first intermediate host, the land snail ''Cochlicopa lubrica'' (synonym: ''Cionella lubrica''). Next came the discovery that the slime balls coughed up by the snails could be a potential method of transfer of the parasite. Shortly thereafter, the ant ''Formica fusca'' was found to be the second intermediate ...

Plagiorchiida
Plagiorchiida is a large order of trematodes, synonymous to Echinostomida. They belong to the Digenea, a large subclass of flukes. This order contains relatively few significant parasites of humans. The following families are placed here, organised by superfamily and suborder:Jones, A., Bray, R. A., & Gibson, D. I. (Eds.). (2002). ''Keys to the Trematoda'' (Vol. 1). CABI Publishing and The Natural History Museum. * Apocreadiata ** Apocreadioidea Skrjabin, 1942 *** Apocreadiidae Skrjabin, 1942 * Bivesiculata ** Bivesiculoidea *** Bivesiculidae Yamaguti, 1934 * Bucephalata ** Bucephaloidea Poche, 1907 *** Bucephalidae Poche, 1907 *** Nuitrematidae Kurochkin, 1975 * Echinostomata ** Echinostomatoidea Looss, 1902 *** Caballerotrematidae Tkach, Kudlai & Kostadinova, 2016 *** Calycodidae Dollfus, 1929 *** Cyclocoelidae Stossich, 1902 *** Echinochasmidae Odhner, 1910 *** Echinostomatidae Looss, 1899 *** Fasciolidae Railliet, 1895 *** Himasthlidae Odhner, 1910 *** Philophthalm ...
