Anaplasma
''Anaplasma'' is a genus of bacteria of the alphaproteobacterial order Rickettsiales, family Anaplasmataceae. ''Anaplasma'' species reside in host blood cells and lead to the disease anaplasmosis. The disease most commonly occurs in areas where competent tick vectors are indigenous, including tropical and semitropical areas of the world for intraerythrocytic ''Anaplasma'' spp.Anaplasmas reviewed and published by , accessed 10 October 2011. ''Anaplasma'' species are biologically transmitted by Ixodes deer-tick vectors, and the prototypical species, ''A. marginale,'' can be mechanically transmitted by biting flies and iatrogenically with blood-contaminat ...

Wolbachia
''Wolbachia'' is a genus of intracellular bacteria that infects mainly arthropod species, including a high proportion of insects, and also some nematodes. It is one of the most common parasitic microbes, and is possibly the most common reproductive parasite in the biosphere. Its interactions with its hosts are often complex, and in some cases have evolved to be mutualistic rather than parasitic. Some host species cannot reproduce, or even survive, without ''Wolbachia'' colonisation. One study concluded that more than 16% of neotropical insect species carry bacteria of this genus, and as many as 25 to 70% of all insect species are estimated to be potential hosts. History The genus was first identified in 1924 by Marshall Hertig and Simeon Burt Wolbach in the common house mosquito. They described it as "a somewhat pleomorphic, rodlike, Gram-negative, intracellular organism hatapparently infects only the ovaries and testes". Hertig formally described the species in 1936, and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Prokaryotic Names With Standing In Nomenclature
List of Prokaryotic names with Standing in Nomenclature (LPSN) is an online database that maintains information on the nomenclature, naming and Taxonomy (biology), taxonomy of prokaryotes, following the taxonomy requirements and rulings of the International Code of Nomenclature of Prokaryotes. The database was curated from 1997 to June 2013 by Jean P. Euzéby. From July 2013 to January 2020, LPSN was curated by Aidan C. Parte. In February 2020, a new version of LPSN was published as a service of the DSMZ, Leibniz Institute DSMZ, thereby also integrating the Prokaryotic Nomenclature Up-to-date service.

Aegyptianella
''Aegyptianella'' is a genus in the phylum Pseudomonadota (Bacteria). Etymology The name ''Aegyptianella'' derives from:New Latin grammatical gender, feminine gender dim. noun ''Aegyptianella'' (from Latin noun ''Aegyptus''), named after Egypt where the organism was described (in 1929). Species The genus contains a single species, namely ''Aegyptianella pullorum, A. pullorum ''(Latin noun ''pullus'', a young fowl, chicken; Latin Latin declension, genitive case pl. noun ''pullorum'', of young fowls.)

Ehrlichia
''Ehrlichia'' is a genus of Rickettsiales bacteria that are transmitted to vertebrates by ticks. These bacteria cause the disease ehrlichiosis, which is considered zoonotic, because the main reservoirs for the disease are animals. ''Ehrlichia'' species are obligately intracellular pathogens and are transported between cells through the host cell filopodia during initial stages of infection, whereas in the final stages of infection, the pathogen ruptures the host cell membrane. History The genus ''Ehrlichia'' is named after German microbiologist Paul Ehrlich. The first ehrlichial disease was recognized in South Africa during the 19th century. Its tick-borne nature was determined in 1900. The organism itself was demonstrated in 1925 when it was recognized to be a ''Rickettsia''. It was initially named ''Rickettsia ruminantium'', and is currently named ''Ehrlichia ruminantium''. In 1945, an "infection and treatment" method for livestock was developed. This is still the only com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyticum
''Lyticum'' is a genus in the phylum Pseudomonadota (Bacteria). Etymology The name ''Lyticum'' derives from:New Latin ''lyticus'' (from Greek ''lutikos, ''λυτικός), able to loosen, able to dissolve; to give ''Lyticum'', dissolver. Species The genus contains two species (including basonyms and synonyms): * '' L. flagellatum'' ( (''ex'' Preer ''et al''. 1974) Preer and Preer 1982, nom. rev.

Neorickettsia
''Neorickettsia'' is a genus of bacteria. Species or strains in this genus are coccoid or pleomorphic cells that reside in cytoplasmic vacuoles within monocytes and macrophages of dogs, horses, bats, and humans. '' Neorickettsia sennetsu'' causes Sennetsu ehrlichiosis. Unlike other forms of ehrlichiosis, ''Neorickettsia sennetsu'' is transmitted by trematodes from fish. '' Neorickettsia risticii'' causes Potomac horse fever Potomac Horse Fever (PHF) is a potentially-fatal febrile illness affecting horses caused by the intracellular bacterium '' Neorickettsia risticii''. PHF is also known as Shasta River Crud and Equine Monocytic Ehrlichiosis. It was first described i .... '' Neorickettsia helminthoeca'' is found in association with the trematode '' Nanophyetus salmincola'', and causes salmon poisoning disease in dogs and other canids.

Bacterium
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rickettsiales
The Rickettsiales, informally called rickettsias, are an order of small Alphaproteobacteria. They are obligate intracellular parasites, and some are notable pathogens, including ''Rickettsia'', which causes a variety of diseases in humans, and '' Ehrlichia'', which causes diseases in livestock. Another genus of well-known Rickettsiales is the ''Wolbachia'', which infect about two-thirds of all arthropods and nearly all filarial nematodes. Genetic studies support the endosymbiotic theory according to which mitochondria and related organelles developed from members of this group.Thomas S. (2016). Rickettsiales:Biology, Molecular Biology, Epidemiology, and Vaccine Development. pp.529. Springer• The Rickettsiales are difficult to culture, as they rely on living eukaryotic host cells for their survival. Rickettsiales phylogeny The Rickettsiales further consist of three known families, the Rickettsiaceae, the Midichloriaceae, and the Ehrlichiaceae. Most studies also support the ...
