Acanthotrema is a genus of trematodes in the family Heterophyidae.
Centrocestus formosanus, or the mystery fluke, is a trematode parasite of Asian origin that has found its way into North American streams and rivers. It not only affects the fountain darter but many species of commercially important fishes. It is also capable of infecting humans
Cyclocoelidae is a family of trematodes in the order Plagiorchiida.
Maritrema heardi is a parasitic fluke that infects the marsh rice rat in a salt marsh at Cedar Key, Florida. It was first listed as Maritrema sp. II in 1988, then described as the only species of a new genus, Floridatrema heardi, in 1994, and eventually reassigned in 2003 to Maritrema as Maritrema heardi. Its intermediate host is the fiddler crab Uca pugilator and it lives in the intestine of the marsh rice rat, its definitive host. Together with two other species of Maritrema, it is very common in affected marsh rice rats; it infects 19% of studied rats at Cedar Key. According to Tkach and colleagues, M. heardi is probably primarily a parasite of birds that has secondarily infected the marsh rice rat. Floridatrema was distinguished from Maritrema on the basis of its possession of loops of the uterus that extend forward to the place where the intestine is forked or even to the pharynx. Genetically, M. heardi may be closest to the morphologically similar M. neomi, which infects Neomys water shrews in the Carpathians.
Ascocotyle pindoramensis is a fluke in the genus Ascocotyle that occurs along the eastern coast of the Americas from Brazil to Nicaragua, Mexico, Louisiana, and Florida and doubtfully in Egypt. It occurs in the intestine of its definitive hosts. Hosts recorded in the wild include the least bittern, roseate spoonbill, great blue heron, striated heron, stripe-backed bittern, yellow-crowned night heron, black-crowned night heron, osprey, Neotropic cormorant, and marsh rice rat. In the marsh rice rat, it infected 9% of rats examined in a 1970–1972 study in the salt marsh at Cedar Key, Florida, but none in a freshwater marsh. A. pindoramensis has been experimentally introduced into the domestic duck, chicken, dog, house mouse, and golden hamster. It occurs in various body parts of its intermediate hosts—the poeciliid fish Phalloptychus januarius, Poecilia catemaconis, Poecilia mexicana, Poecilia mollienisicola, Poecilia vivipara, and a species of Xiphophorus and the cichlid Tilapia. It was first described as Pygidiopsis pindoramensis in 1928 and subsequently as Pseudoascocotyle mollienisicola in 1960. The latter species was moved to Ascocotyle in 1963, but only in 2006 it was recognized that the two represent the same species, which is now known as Ascocotyle pindoramensis. Other flukes from Argentina and Mexico that were identified as Pygidiopsis pindoramensis instead represent a different species of Pygidiopsis.
Maritrema is a genus of trematodes (flukes) in the family Microphallidae, although some have suggested its placement in the separate family Maritrematidae. It was first described by Nikoll in 1907 from birds in Britain. Species of the genus usually infect birds, but several have switched hosts and are found in mammals, such as the marsh rice rat. Several species use the fiddler crab Uca pugilator as an intermediate host.
Acanthotrema cursitans is a species of fluke in the genus Acanthotrema. It infects the marsh rice rat Oryzomys palustris, the raccoon Procyon lotor, the Virginia opossum Didelphis virginiana, the snail Cerithidea scalariformis, and killifishes of the genus Fundulus on the Gulf Coast of Florida. It was first described as Cercaria cursitans in 1961, then moved to Stictodora in 1974, and to Acanthotrema in 2003.
Heterophyidae is a family of intestinal trematodes in the order Plagiorchiida.
Opecoelidae is a family of trematodes. It is the largest digenean family with over 90 genera and nearly 900 species, almost solely found in marine and freshwater teleost fishes. It was considered by Bray et al. to belong in the superfamily Opecoeloidea Ozaki, 1925 or the Brachycladioidea Odhner, 1905.
Metagonimus miyatai is a species of a trematode, or fluke worm, in the family Heterophyidae.
Allopodocotyle is a genus of trematodes in the family Opecoelidae.
Coitocaecum is a genus of trematodes in the family Opecoelidae. It has been synonymised to Ozakia Wisniewski, 1934, Paradactylostomum Zhukov, 1972 nec Toman, 1992, and Pseudocoitocaecum Bilqees, 1972.
Dactylostomum is a genus of trematodes in the family Opecoelidae. It is synonyised with Opedunculata Dwivedi, 1975.
Helicometra is a genus of trematodes in the class Opecoelidae. It is synonymous with AllostenoperaBaeva, 1968, MetahelicometraYamaguti, 1971, and StenoperaManter, 1933. Its type species is H. fasciata(Rudolphi, 1819). They are distinguished by their unique spiral uterus, from which their name is derived.
Neolebouria is a genus of trematodes in the family Opecoelidae.
Opecoeloides is a genus of trematodes in the family Opecoelidae. It has been synonymised with Cymbephallus Linton, 1934 and Fimbriatus von Wicklen, 1946.
Peracreadium is a genus of trematodes in the family Opecoelidae. It is very similar to the related genus Cainocreadium Nicoll, 1909, and has been synonymised with the genera Anabathycreadium Salman & Srivastava, 1990, Indocreadium Salman & Srivastava, 1990, and Lebouria Nicoll, 1909.
Pseudopecoelus is a genus of trematodes in the family Opecoelidae. It has been synonymised with Neopecoelus Manter, 1947.
Opistholebes is a genus of trematodes in the family Opecoelidae.
