Opisthorchis
''Opisthorchis'' is a genus of flukes in the family Opisthorchiidae. Species Species in the genus ''Opisthorchis'' include: * '' Opisthorchis chabaudi'' Bourgat & Kulo, 1977 * ''Opisthorchis felineus'' (Rivolta, 1884) * '' Opisthorchis gomtii'' Mehra, 1941 * '' Opisthorchis parasiluri'' Long & Lee * ''Opisthorchis viverrini'' Poirier, 1886 The species known as ''Clonorchis sinensis'' has sometimes been reclassified into the genus ''Opisthorchis''. Etymology From the Greek opisthen (behind) and orchis (testicle), Opisthorchis is a genus of trematode flatworms whose testes are located in the posterior end of the body. Sebastiano Rivolta is generally credited with discovering the first opisthorchid, which he named Distoma felineus, in a cat in Italy in 1884. However, the fluke may have been mentioned by Karl Rudolphi in 1819, and in 1831, Gurlt published a textbook that included a drawing of a fluke that was almost certainly Opisthorchis.

Opisthorchis Viverrini
''Opisthorchis viverrini'', common name Southeast Asian liver fluke, is a food-borne trematode parasite from the family Opisthorchiidae that infects the bile duct. People are infected after eating raw or undercooked fish. Infection with the parasite is called opisthorchiasis. ''O. viverrini'' infection also increases the risk of cholangiocarcinoma, a cancer of the bile ducts. A small, leaf-like fluke, ''O. viverrini'' completes its lifecycle in three different animals. Snails of the species ''Bithynia'' are the first intermediate hosts, fish belonging to the family Cyprinidae are the second intermediate host, and the definitive hosts are humans and other mammals such as dogs, cats, rats, and pigs. It was first discovered in the Indian fishing cat (''Prionailurus viverrus'') by M.J. Poirier in 1886. The first human case was discovered by Robert Thomson Leiper in 1915. ''O. viverrini'' (together with ''Clonorchis sinensis'' and ''Opisthorchis felineus'') is one of the three mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Opisthorchis Felineus
''Opisthorchis felineus'', or cat liver fluke is a trematode parasite that infects the liver in mammals. It was first discovered in 1884 in a cat's liver by Sebastiano Rivolta of Italy. In 1891, Russian parasitologist, Konstantin Nikolaevich Vinogradov (1847–1906) found it in a human, and named the parasite a "Siberian liver fluke". In the 1930s, helminthologist Hans Vogel of Hamburg published an article describing the life cycle of ''Opisthorchis felineus''. Bernhard Nocht Institute for Tropical Medicine Felineus infections may also involve the pancreatic ducts. Diagnosis of Opisthorchis infection is based on microscopic identification of parasite eggs in stool specimens. Safe and effective medication is available to treat Opisthorchis infections.

Distoma Felineus
Liver fluke is a collective name of a polyphyletic group of parasitic trematodes under the phylum Platyhelminthes. They are principally parasites of the liver of various mammals, including humans. Capable of moving along the blood circulation, they can occur also in bile ducts, gallbladder, and liver parenchyma. In these organs, they produce pathological lesions leading to parasitic diseases. They have complex life cycles requiring two or three different hosts, with free-living larval stages in water. Biology The body of liver flukes is leaf-like and flattened. The body is covered with a tegument. They are hermaphrodites having complete sets of both male and female reproductive systems. They have simple digestive systems and primarily feed on blood. The anterior end is the oral sucker opening into the mouth. Inside, the mouth leads to a small pharynx which is followed by an extended intestine that runs through the entire length of the body. The intestine is heavily branched and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opisthorchiidae
Opisthorchiidae is a family of digenean trematodes. Opisthorchiidae have cosmopolitan distribution. The most medically important species in the family Opisthorchiidae are ''Clonorchis sinensis'', ''Opisthorchis viverrini'', and '' Opisthorchis felineus'', that are causes of the disease clonorchiasis. Some species are parasites of economically important fish, e.g. ''Clarias gariepinus''.Jansen van Rensburg, C., van As, J.G. & King, P.H. 2013.

Clonorchis Sinensis
''Clonorchis sinensis'', the Chinese liver fluke, is a liver fluke belonging to the class Trematoda, phylum Platyhelminthes. It infects fish-eating mammals, including humans. In humans, it infects the common bile duct and gall bladder, feeding on bile. It was discovered by British physician James McConnell at the Medical College Hospital in Calcutta (Kolkata) in 1874. The first description was given by Thomas Spencer Cobbold, who named it ''Distoma sinense''. The fluke passes its lifecycle in three different hosts, namely freshwater snail as first intermediate hosts, freshwater fish as second intermediate host, and mammals as definitive hosts. Endemic to Asia and Russia, ''C. sinensis'' is the most prevalent human fluke in Asia and third-most in the world. It is still actively transmitted in Korea, China, Vietnam, and Russia. Most infections (about 85%) occur in China. The infection, called clonorchiasis, generally appears as jaundice, indigestion, biliary inflammation, bile duct ...

Trematode
Trematoda is a class of flatworms known 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 usually a snail. The definitive host, where the flukes sexually reproduce, is a vertebrate. Infection by trematodes can cause disease in all five traditional vertebrate classes: mammals, birds, amphibians, reptiles, and fish. 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. Taxonomy There are 18,000 to 24,000 known species of trematodes, divided into two subclasses — the Aspidogastrea and the Digenea. Aspidogastrea is the smaller subclass, comprising 61 species. These flukes mainly infect bivalves and bony fishes.https://www.biotaxa.org/Zootaxa/article/view/zootaxa.3918.3.2 Digenea — which comprise the majority of trematodes — ...

Raphaël Blanchard
Raphaël Anatole Émile Blanchard (28 February 1857 – 7 February 1919) was a French physician and naturalist who was a pioneer of medical zoology, with studies on parasites ranging from protozoa to worms and insects. Blanchard was born in Saint-Christophe-sur-le-Nais. He was a great grand nephew of the balloonist and parachute inventor Jean Pierre Blanchard. He went to study medicine in Paris in 1874. He became interested in zoology and worked at the laboratory at the École des Hautes-Études where he became a histological preparator for Charles Robin and Georges Pouchet, the latter influencing him towards studies on experimental teratology (inducing mutations and malformations). He travelled around Europe in 1877 with a grant from the Paris City Council, studying embryology in Vienna and comparative anatomy in Bonn. He received another grant in 1880 to study the organization of universities and biological education across Europe. He wrote a dissertation on anesthesia induced by ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...
