Echinostoma
''Echinostoma'' is a genus of trematodes (flukes), which can infect both humans and other animals. These intestinal flukes have a three-host life cycle with snails or other aquatic organisms as intermediate hosts, and a variety of animals, including humans, as their definitive hosts. ''Echinostoma'' infect the gastrointestinal tract of humans, and can cause a disease known as echinostomiasis. The parasites are spread when humans or animals eat infected raw or undercooked food, such as bivalve molluscs or fish. Taxonomy There has been debate about the number of species in this group, with estimates as high as 120 unique species of ''Echinostoma'', however, currently 16 species have been accepted as valid species with another 10 to be validated ''Echinostoma'' are difficult to classify based on morphology alone. Many species look alike and can be considered cryptic species (different lineages are considered to be the same species, due to high morphological similarity between ...

Echinostoma Revolutum
''Echinostoma revolutum'' is a trematode parasites, of which the adults can infect birds and mammals, including humans. In humans, it causes echinostomiasis.. Distribution ''Echinostoma revolutum'' is the most widely distributed species of the known 20 Echinostomatidae species; it is found in Asia, Oceania, Europe, and the Americas. In Asian countries the disease is endemic to humans. Outbreaks have been reported in North America after travellers returend from Kenya and Tanzania. Description The worms are leaflike, elongated, and an average of 8.8 mm long (8.0–9.5 mm) and 1.7 mm wide (1.2–2.1 mm). When first passed in the feces, they were pinkish red and coiled in a "c" or "e" shape. The eggs in uteri were an average of 105 μm long (97–117 μm) and 63 μm wide (61–65 μm). Life cycle Infection of ''Echinostoma revolutum'' usually results from ingestion of raw snails or frogs that serve as an intermediate host. This parasite is predominantly foun ...

Echinostoma Miyagawai
''Echinostoma miyagawai'' is a species of echinostome parasite that is found in Europe, Southeast Asia and Japan. It can use multiple aquatic snail species as first intermediate host, such as ''Planorbis planorbis'', '' Anisus vortex'', and ''Radix peregra''. The definitive host species include the wild duck, the tufted duck, the domestic chicken, and the brown rat. In the definitive host it resides in the small intestine, cecum, and rectum. In Thailand and Laos ''E. miyagawai'', is more common parasite of free-living ducks than '' E. revolutum''. Taxonomy Genetic analysis has shown that the species can be subdivided into two different lineages; a Eurasian lineage and an Australian lineage. The latter includes individuals from Australia and the Americas. Genetic exchange within these lineages over such long distances is possible through distribution by birds. However, it has also been suggested that the Eurasian lineage might actually present a distinct species. Furthermore, ...

Echinostoma Cinetorchis
''Echinostoma cinetorchis'' is a species of human intestinal fluke, a trematode in the family Echinostomatidae. Distribution This species occurs in Korea. Hosts Hosts of ''Echinostoma cinetorchis'' include: * ''Cipangopaludina chinensis'' (Gray, 1834) – Chinese mystery snail, an intermediate host * ''Austropeplea ollula'' – as a first and main intermediate host * Note on ''Hippeutis (Helicorbis) cantori'' – this species had previously been reported as first and second intermediate host, but in a subsequent study in a laboratory setting, the species was not able to be infected at all. * '' Segmentina hemispaerula'' as a first and second intermediate host in Korea, based on laboratory work. * '' Gyraulus convexiusculus'' as a potential first and second intermediate host in Korea, based on laboratory work. Experimentally induced infection of host species that occur in Korea in a laboratory setting include: From miracidia to cercaria, i.e. as a primary intermediate host: *'' ...

Echinostoma Caproni
''Echinostoma caproni'' is a species of 37-spined Egyptian echinostome. It is naturally found in Cameroon, Congo, Egypt, Madagascar, and Togo. ''Echinostoma caproni'' uses different snails species as first and second intermediate hosts, like ''Biomphalaria'' species and ''Pseudosuccinea columella''. It can use different rodents, such as mice, rats and the african giant shrew, as definitive hosts. However, the suitability of these definitive hosts varies markedly. In the definitive host the metacercariae excyst in the duodenum. The juvenile worms then move down to the ileum. About ten days after infection, ''E. caproni'' eggs appear in the host faeces. The eggs then take another ten days to develop, before miracidia appear from them. These miracidia remain infective for 8 hours after hatching. In mice, a single oral doses of praziquantel, artesunate, or artemether Artemether is a medication used for the treatment of malaria. The injectable form is specifically used for se ...

Trematoda
Trematoda is a Class (biology), class of flatworms known as flukes. They are obligate parasite, obligate internal Parasitism, parasites with a complex biological life cycle, life cycle requiring at least two Host_(biology), 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 Bivalvia, bivalves and Osteichthyes, bony fishes.https://www.bi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
