Echinostoma Chloephagae
''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 t ...

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: *'' ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ...

Phylogenetic Tree
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to b ...
