M. Mycoides
''Mycoplasma mycoides'' is a bacterial species of the genus ''Mycoplasma'' in the class Mollicutes. This microorganism is a parasite that lives in ruminants. ''Mycoplasma mycoides'' comprises two subspecies, '' mycoides'' and ''capri'', which infect cattle and small ruminants such as goats respectively. ''Mycoplasma mycoides'' subsp. ''mycoides'' The subspecies "''Mycoplasma mycoides'' subsp. ''mycoides'' (Mmm)", previously named "''Mycoplasma mycoides'' subsp. ''mycoides'' Small Colony (SC) type (MmmSC)", is known as the agent of contagious bovine pleuropneumonia (CBPP), a contagious lung disease of cattle. It was first isolated in 1898 by Edmond Nocard et al. and the first mycoplasma to be isolated at all. Formerly, ''M. mycoides'' subsp. ''mycoides'' was known as ''Asterococcus mycoides''. The ''Mycoplasma mycoides'' cluster ''Mycoplasma mycoides'' belongs to the ''Mycoplasma mycoides'' cluster, or ''Mycoplasma mycoides'' group, a group of closely related infectious mycopla ...

Amédée Borrel
Amédée Marie Vincent Borrel (1 August 1867 – 14 September 1936) was a French physician and microbiologist born in Cazouls-lès-Béziers, Hérault. Biography Borrel studied natural sciences and medicine at the University of Montpellier, where he earned his degree in 1890. From 1892 to 1895, Borrel worked in the laboratory of Ilya Ilyich Metchnikoff (1845–1916) at the Pasteur Institute in Paris. Here he performed research of tuberculosis, and with Alexandre Yersin (1863–1943) and Léon Charles Albert Calmette (1863–1933), he worked on a vaccine against bubonic plague. With Yersin and Calmette, he co-published the treatise ''Le microbe de la peste à bubons'' concerning the plague bacillus. He is also credited for pioneer investigations on the viral theory of cancer. From 1896 to 1914 he served as laboratory chief of the microbiology course at the Pasteur Institute. In 1919 he attained the chair of bacteriology at the University of Strasbourg. A genus of bacteria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryozoa
Psychrophiles or cryophiles (adj. ''psychrophilic'' or ''cryophilic'') are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from to . They have an optimal growth temperature at . They are found in places that are permanently cold, such as the polar regions and the deep sea. They can be contrasted with thermophiles, which are organisms that thrive at unusually high temperatures, and mesophiles at intermediate temperatures. Psychrophile is Greek for 'cold-loving', . Many such organisms are bacteria or archaea, but some eukaryotes such as lichens, snow algae, phytoplankton, fungi, and wingless midges, are also classified as psychrophiles. Biology Habitat The cold environments that psychrophiles inhabit are ubiquitous on Earth, as a large fraction of the planetary surface experiences temperatures lower than 10 °C. They are present in permafrost, polar ice, glaciers, snowfields and deep ocean waters. These organisms can also be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minimal Genome Project
''Mycoplasma laboratorium'' or Synthia refers to a synthetic strain of bacterium. The project to build the new bacterium has evolved since its inception. Initially the goal was to identify a minimal set of genes that are required to sustain life from the genome of ''Mycoplasma genitalium'', and rebuild these genes synthetically to create a "new" organism. ''Mycoplasma genitalium'' was originally chosen as the basis for this project because at the time it had the smallest number of genes of all organisms analyzed. Later, the focus switched to ''Mycoplasma mycoides'' and took a more trial-and-error approach. To identify the minimal genes required for life, each of the 482 genes of ''M. genitalium'' was individually deleted and the viability of the resulting mutants was tested. This resulted in the identification of a minimal set of 382 genes that theoretically should represent a minimal genome. In 2008 the full set of ''M. genitalium'' genes was constructed in the laboratory wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycoplasma Capricolum Subsp
''Mycoplasma'' is a genus of bacteria that, like the other members of the class ''Mollicutes'', lack a cell wall around their cell membranes. Peptidoglycan (murein) is absent. This characteristic makes them naturally resistant to antibiotics that target cell wall synthesis (like the beta-lactam antibiotics). They can be parasitic or saprotrophic. Several species are pathogenic in humans, including '' M. pneumoniae'', which is an important cause of "walking" pneumonia and other respiratory disorders, and '' M. genitalium'', which is believed to be involved in pelvic inflammatory diseases. ''Mycoplasma'' species (like the other species of the class ''Mollicutes'') are among the smallest organisms yet discovered, can survive without oxygen, and come in various shapes. For example, ''M. genitalium'' is flask-shaped (about 300 x 600 nm), while ''M. pneumoniae'' is more elongated (about 100 x 1000 nm), many ''Mycoplasma'' species are coccoid.

Mycoplasma Capricolum
''Mycoplasma capricolum'' is a species of Mycoplasma bacteria. It is primarily a pathogen of goats, but has also been found in sheep and cows. The species requires external sources of cholesterol to grow or survive (which usually comes in the form of a natural fatty acid auxotroph), but the uptaken fatty acid is not used as a substrate for energy production but rather for phospholipid synthesis instead. It causes a disease in goats called contagious caprine pleuropneumonia {{Taxobox , name = ''Mycoplasma capricolum'' subsp.

Sensu Stricto
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: *''sensu stricto'' – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; *''sensu lato'' – "in the broad sense", abbreviation ''s.l.''; *''sensu amplo'' – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edmond Nocard
Edmond Isidore Etienne Nocard (29 January 1850 – 2 August 1903), was a French veterinarian and microbiologist, born in Provins (Seine-et-Marne, France). Nocard studied veterinary medicine from 1868 to 1871 and (after a brief service in the Army) from 1871 to 1873 in the École Vétérinaire de Maisons-Alfort. From 1873 to 1878 he was hired as Head of Clinical Service at the same school, working with Dumesnil. In 1876 he is charged with the creation of a new journal, the ''Archives Vétérinaires''. In this journal, Nocard will publish a great number of scientific papers, on medicine, surgery, hygiene and jurisprudence. In 1878 he is approved in a public contest as Professor of Clinical and Surgical Veterinary of the École Veterinaire. Among his many pupils who became famous was Camille Guérin, co-discoverer of the Bacillus Calmette-Guérin (BCG). In 1880 Nocard entered the laboratory of Louis Pasteur in Paris as an assistant. There, he helped Pasteur and Emile Roux in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contagious Bovine Pleuropneumonia
Contagious bovine pleuropneumonia (CBPP – also known as lung plague), is a contagious bacterial disease that afflicts the lungs of cattle, buffalo, zebu, and yaks. It is caused by the bacterium ''Mycoplasma mycoides'', and the symptoms are pneumonia and inflammation of the lung membranes. The incubation period is 20 to 123 days. It was particularly widespread in the United States in 1879, affecting herds from several states. The outbreak was so severe that it resulted in a trade embargo by the British government, blocking U.S. cattle exports to Britain and Canada. This prompted the United States to establish the Bureau of Animal Industry, set up in 1884 to eradicate the disease, which it succeeded in doing by 1892. Louis Willems, a Belgian doctor, began pioneering work in the 1850s on animal inoculation against the disease. The bacteria are widespread in Africa, the Middle East, Southern Europe, as well as parts of Asia. It is an airborne species, and can travel up to several k ...
