Genarchopsis goppo is a species of a trematode, or fluke worm, in the family Derogenidae. [1]
Trematoda is a class within the phylum [[Platyhelmi nthes]]. It includes two groups of parasitic flatworms, known as flukes.
Genarchopsis goppo was classified within the family Hemiuridae. [2]
The first intermediate hosts of Genarchopsis goppo include freshwater snails Amnicola travancorica [2] and Semisulcospira libertina . [1]
Semisulcospira libertina is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Semisulcospiridae. Widespread in east Asia, it lives in China, Taiwan, Korea, Japan, and the Philippines. In some countries it is harvested as a food source. It is medically important as a vector of clonorchiasis, paragonimiasis, metagonimiasis and others.
The second intermediate hosts include ostracods Stenocypris malcolmsoni , Eucyoris capensis , [2] copepods Mesocyclops leuckarti , Thermocyclops hyalinus and Eucyclops sarrulatus . [1]
Hosts of Genarchopsis goppo include fish: the spotted snakehead Channa punctata , [2] Rhinogobius sp. and Odontobutis obscura . [1]
Channa punctata, the spotted snakehead, is a species of snakehead. It is found in the Indian Subcontinent and nearby areas, ranging across Afghanistan, Pakistan, India, Sri Lanka, Nepal, Bangladesh, Myanmar and Tibet. Its natural habitats are swamps, ponds and brackish water systems. It is a fish of high food value and has little value as aquarium fish.
Rhinogobius is a genus of primarily freshwater gobies native to tropical and temperate parts of eastern Asia. Most are small, streamlined in shape, and often sexually dimorphic. Few are of commercial importance, but R. duospilus is fairly widely traded as an aquarium fish.
Paratenic hosts include fish Aplocheilus panchax . [2]
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 are particularly common in 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 Aspidogastrea is a small group of flukes comprising about 80 species. It is a subclass of the trematoda, and sister group to the Digenea. Species range in length from approximately one millimeter to several centimeters. They are parasites of freshwater and marine molluscs and vertebrates. Maturation may occur in the mollusc or vertebrate host. None of the species has any economic importance, but the group is of very great interest to biologists because it has several characters which appear to be archaic.
Fasciolidae is a family of trematodes and includes several parasites involved in the veterinary and medical sciences. Fasciolidae is divided into five genera by Olsen et al. 2003. The family's various species are localised in liver, gall bladder, and intestine. Their life-cycle includes an intermediate host, freshwater snails from the family Lymnaeidae.
Metagonimoides oregonensis is a trematode, or fluke worm, in the family Heterophyidae. This North American parasite is found primarily in the intestines of raccoons, American minks, frogs in the genus Rana, and freshwater snails in the genus Goniobasis. It was first described in 1931 by E. W. Price. The parasite has a large distribution, from Oregon to North Carolina. Adult flukes vary in host range and morphology dependent on the geographical location. This results in different life cycles, as well as intermediate hosts, across the United States. On the west coast, the intermediate host is freshwater snails (Goniobasis), while on the east coast the intermediate host is salamanders (Desmognathus). The parasites on the west coast are generally much larger than on the east coast. For example, the pharynx as well as the body of the parasite are distinctly larger in Oregon than in North Carolina. The reverse pattern is observed on the east coast for uterine eggs, which are larger on the west coast. In snails, there is also a higher rate of infection in female snails than in males. Research on the life history traits of the parasites have been performed with hamsters and frogs as model species.
Austropeplea ollula is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae, the pond snails.
Echinostoma cinetorchis is a species of human intestinal fluke, a trematode in the family Echinostomatidae.
Clinostomum marginatum is a species of parasitic fluke. It is commonly called the "yellow grub". It is found in many freshwater fish in North America, and no fish so far is immune to this parasite. This type of fluke can also be found in the mouth of aquatic birds such as herons and egrets. They are commonly present in the esophagus of fish-eating birds and reptiles. Eggs of these trematodes are shed in the feces of aquatic birds and released into water. Aquatic birds become hosts of this parasite by ingesting infected freshwater fish. The metacercariae are found right beneath the skin or in the muscles of host fish.
The Bucephaloidea are a superfamily of trematode flatworms, belonging to the large group Digenea. Many species are endoparasites of mollusks and fish. The name Bucephalus meaning "ox head" was originally applied to the genus Bucephalus because of the horn-like appearance of the forked tail (furcae) of its cercaria larva. By what Manter calls a "curious circumstance", horns are also suggested by the long tentacles of adult worms.
Bucephalidae is a family of trematodes that parasitize fish. They lack suckers, having instead a muscular organ called a "rhynchus" at the front end which they use to attach to their hosts. The characteristics of the rhynchus are used to help define the genera of the family. It is one of the largest digenean families, with 25 genera containing hundreds of described species. Bucephalids are cosmopolitan, having been recorded all over the world. They are parasites of fish from freshwater, marine, and brackish water habitat types.
Nicolla skrjabini is a species of trematodes in the family Opecoelidae.
Haplorchis taichui is a species of intestinal fluke in the family Heterophyidae. It is a human parasite.
Metagonimus yokogawai is a species of a trematode, or fluke worm, in the family Heterophyidae.
Liolope copulans is a species of a trematodes, or fluke worms, in the family Liolopidae.
Eucreadium is a genus of trematodes in the family Opecoelidae.
Bivesiculidae is a family of trematodes in the order Plagiorchiida.
Gyraulus convexiusculus is a species of freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.
