Archamoebae
The Archamoebae are a group of protists originally thought to have evolved before the acquisition of mitochondria by eukaryotes. They include genera that are internal parasites or commensals of animals (''Entamoeba'' and ''Endolimax''). A few species are human pathogens, causing diseases such as amoebic dysentery. The other genera of archamoebae live in freshwater habitats and are unusual among amoebae in possessing flagella. Most have a single nucleus and flagellum, but the giant amoeba '' Pelomyxa'' has many of each. Description Archamoebae are a diverse group of amoebae. Many have flagella for motility, while others do not. They grow in the absence of oxygen, though some can tolerate small amounts. Most described species of Archamoebae either lack mitochondria or are described to have reduced mitosomes. Habitat They thrive and live in soil, freshwater, and marine habitats. History The group Archamoebae was proposed by Thomas Cavalier-Smith in 1998 as part of the Archezoa, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pelomyxa
''Pelomyxa'' is a genus of giant flagellar amoebae, usually 500-800 μm but occasionally up to 5 mm in length, found in anaerobic or microaerobic bottom sediments of stagnant freshwater ponds or slow-moving streams.Chistyakova, L. V., and A. O. Frolov. "Light and electron microscopic study of Pelomyxa stagnalis sp. n.(Archamoebae, pelobiontida)." Cell and Tissue Biology 5.1 (2011): 90-97. The genus was created by R. Greeff, in 1874, with ''Pelomyxa palustris'' as its type species. In the decades following the erection of ''Pelomyxa'', researchers assigned numerous new species to it. However, in the last quarter of the 20th century, investigators reduced the genus to a single species, ''Pelomyxa palustris'', which was understood to be a highly changeable organism with a complex life cycle, whose various phases had been mistaken for separate species. All described species were relegated to the status of synonyms, or moved to the unrelated genus ''Chaos''. Since 2004, four new ...

Entamoeba
''Entamoeba'' is a genus of Amoebozoa found as internal parasites or commensals of animals. In 1875, Fedor Lösch described the first proven case of amoebic dysentery in St. Petersburg, Russia. He referred to the amoeba he observed microscopically as ''Amoeba coli''; however, it is not clear whether he was using this as a descriptive term or intended it as a formal taxonomic name. The genus ''Entamoeba'' was defined by Casagrandi and Barbagallo for the species '' Entamoeba coli'', which is known to be a commensal organism. Lösch's organism was renamed ''Entamoeba histolytica'' by Fritz Schaudinn in 1903; he later died, in 1906, from a self-inflicted infection when studying this amoeba. For a time during the first half of the 20th century the entire genus ''Entamoeba'' was transferred to '' Endamoeba'', a genus of amoebas infecting invertebrates about which little is known. This move was reversed by the International Commission on Zoological Nomenclature in the late 1950s, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrion
A mitochondrion (; ) is an organelle found in the cells of most Eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. They were discovered by Albert von Kölliker in 1857 in the voluntary muscles of insects. The term ''mitochondrion'' was coined by Carl Benda in 1898. The mitochondrion is popularly nicknamed the "powerhouse of the cell", a phrase coined by Philip Siekevitz in a 1957 article of the same name. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells). A large number of unicellular organisms, such as microsporidia, parabasalids and diplomonads, have reduced or transformed their mitochondria into other structures. One eukaryote, ''Monocercomonoides'', is known to have completely lost its mitochondria, and one multicellular organism, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
