Trematoda is a class within the phylum Platyhelminthes. It includes two groups of parasitic flatworms, known as flukes.
Digenea is a class of trematodes in the Platyhelminthes phylum, consisting of parasitic flatworms with a syncytial tegument and, usually, two suckers, one ventral and one oral. Adults commonly live within the digestive tract, but occur throughout the organ systems of all classes of vertebrates. Once thought to be related to the Monogenea, it is now recognised that they are closest to the Aspidogastrea and that the Monogenea are more closely allied with the Cestoda. Around 6,000 species have been described to date.
The little brown bat or little brown myotis is a species of mouse-eared microbat found in North America. It has a small body size and glossy brown fur. It is similar in appearance to several other mouse-eared bats, including the Indiana bat, northern long-eared bat, and Arizona myotis, to which it is closely related. Despite its name, the little brown bat is not closely related to the big brown bat, which belongs to a different genus.
Fasciolopsis is a genus of trematodes. They are also known as the intestinal flukes.
Philophthalmus gralli, commonly known as the Oriental avian eye fluke, parasitises the conjunctival sac of the eyes of many species of birds, including birds of the orders Galliformes and Anseriformes. In Brazil this parasite was reported in native Anseriformes species. It was first discovered by Mathis and Leger in 1910 in domestic chickens from Hanoi, Vietnam. Birds are definitive hosts and freshwater snail species are intermediate hosts. Human cases of philophthalmosis are rare, but have been previously reported in Europe, Asia, and America.
Homalometron pallidum is a species of marine trematodes in the family Apocreadiidae. It is an endoparasite of the mummichog, Fundulus heteroclitus, a small fish found in brackish water along the east coast of the United States and Canada. It has a complex life cycle and lives inside several different host species at different stages.
Gastrodiscoides is genus of zoonotic trematode under the class Trematoda. It has only one species, Gastrodiscoides hominis. It is a parasite of a variety of vertebrates, including humans. The first definitive specimen was described from a human subject in 1876. It is prevalent in Bangladesh, India, Burma, China, Kazakhstan, Philippines, Thailand, Vietnam, and the Volga Delta of Russia, with isolated cases from Africa, such as Nigeria. It is especially notable in the Assam, Bengal, Bihar, Madhya Pradesh, Orissa and Uttar Pradesh regions of India.
Pseudorhabdosynochus americanus is a diplectanid monogenean parasitic on the gills of groupers. It was described as Diplectanum americanum by Price in 1937 and transferred to the genus Pseudorhabdosynochus by Kritsky and Beverley-Burton in 1986. The species was redescribed by Kritsky, Bakenhaster and Adams in 2015.
Pseudorhabdosynochus justinella is a diplectanid monogenean parasitic on the gills of the red grouper, Epinephelus morio. It has been described by Kritsky, Bakenhaster and Adams in 2015.
Pseudorhabdosynochus kritskyi is a diplectanid monogenean parasitic on the gills of the gag, Mycteroperca microlepis. The species has been described by Dyer, Williams and Bunkley-Williams in 1995 and redescribed successively by Yang, Gibson and Zeng in 2005 and by Kritsky, Bakenhaster and Adams in 2015. The name of the species honours the American parasitologist Delane C. Kritsky.
Telorchis is a genus of trematode parasites found in many herps, comprising around 70 species. This parasite is an indirect parasite, with a snail intermediate host and a reptile or amphibian definitive host. Typically found in the gastrointestinal tract of their definitive host, telorchids attach to the wall of the intestinal tract with their ventral sucker, or acetabulum.
Biospeedotrema jolliveti is a species of trematodes inhabiting hydrothermal vent fishes in the south eastern Pacific Ocean. It can be distinguished from its family by its symmetrical testicular configuration; its uterus passing between the testes. Furthermore, it can be differentiated by vitelline fields which extend slightly into its post-testicular region; its intestinal bifurcation is dorsal to its ventral sucker; its genital pore is somewhat submedian or median; its cirrus sac is short and the caeca are large and overlap the testes.
Leptotrombidium myotis is a species of mites in the family Trombiculidae that parasitizes bats. Species that it affects include the Arizona myotis, little brown bat, and northern long-eared bat.
Microcotyle constricta is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Microcotylidae.
Microcotyle elegans is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Microcotylidae.
Microcotyle mouwoi is a species of monogenea, parasitic on the gills of a marine fish. It belongs to the family Microcotylidae.
Microcotyle stenotomi is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Microcotylidae and was first described by Goto in 1899.
Microcotyle pempheri is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Microcotylidae.
Sibitrema is a genus which belongs to the phylum Platyhelminthes and class Monogenea; the only species included in this genus is parasite of fish.
Allopseudaxine yaito is a species of monogenean flatworm, which is parasitic on the gills of a marine fish. It belongs to the family Axinidae.
