Roseomonas Gilardii
''Roseomonas gilardii'' is a species of Gram negative, strictly aerobic, coccobacilli-shaped, pink-pigmented bacterium. It is the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen( ... of the genus '' Roseomonas''. The new species was among the first ''Roseomonas'' species proposed in 1993, and is named for "Gerald L. Gilardi for his many contributions to bacteriology and, specifically, for his contributions in the area of glucose-nonfermenting gram-negative rods." ''R. gilardii'' is pathogenic for humans, causing bacteremia and other infections. There are two subspecies of ''R. gilardii'': ''R''. g. subsp. ''gilardii'' and ''R''. g. subsp. ''rosea''.Sanchez-Porro C, Gallego V, Busse HJ, Kämpfer P, Ventosa ATransfer of Teichococcus ludipueritiae and Muricoccus roseus to t ...

Bacteria
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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudomonadota
Pseudomonadota (synonym Proteobacteria) is a major phylum of Gram-negative bacteria. The renaming of phyla in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as '' Escherichia'', '' Salmonella'', '' Vibrio'', '' Yersinia'', '' Legionella'', and many others.Slonczewski JL, Foster JW, Foster E. Microbiology: An Evolving Science 5th Ed. WW Norton & Company; 2020. Others are free-living (non parasitic) and include many of the bacteria responsible for nitrogen fixation. Carl Woese established this grouping in 1987, calling it informally the "purple bacteria and their relatives". Because of the great diversity of forms found in this group, it was later informally named Proteobacteria, after Proteus, a Greek god of the sea capable of assuming many different shapes (not after the Proteobacteria genus ''Proteus''). In 2021 the In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alphaproteobacteria
Alphaproteobacteria is a class of bacteria in the phylum Pseudomonadota (formerly Proteobacteria). The Magnetococcales and Mariprofundales are considered basal or sister to the Alphaproteobacteria. The Alphaproteobacteria are highly diverse and possess few commonalities, but nevertheless share a common ancestor. Like all ''Proteobacteria'', its members are gram-negative and some of its intracellular parasitic members lack peptidoglycan and are consequently gram variable. Characteristics The Alphaproteobacteria are a diverse taxon and comprises several phototrophic genera, several genera metabolising C1-compounds (''e.g.'', ''Methylobacterium'' spp.), symbionts of plants (''e.g.'', '' Rhizobium'' spp.), endosymbionts of arthropods (''Wolbachia'') and intracellular pathogens (''e.g. Rickettsia''). Moreover, the class is sister to the protomitochondrion, the bacterium that was engulfed by the eukaryotic ancestor and gave rise to the mitochondria, which are organelles in eukaryoti ...

Rhodospirillales
The Rhodospirillales are an order of Pseudomonadota. Notable Families The '' Acetobacteraceae'' comprise the acetic acid bacteria, which are heterotrophic and produce acetic acid during their respiration.Garrity, George M.; Brenner, Don J.; Krieg, Noel R.; Staley, James T. (eds.) (2005). Bergey's Manual of Systematic Bacteriology, Volume Two: The Proteobacteria, Part C: The Alpha-, Beta-, Delta-, and Epsilonproteobacteria. New York, New York: Springer. . The ''Rhodospirillaceae'' include mainly purple nonsulfur bacteria, which produce energy through photosynthesis Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored i .... Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN).

Acetobacteraceae
Acetobacteraceae is a family of Gram-negative bacteria, belonging to the order Rhodospirillales, class Alphaproteobacteria. Two distinct clades are recognized. The acetic acid bacteria and a more heterogeneous group including acidophilic and phototrophic bacteria. The type genus is ''Acetobacter''. Ten genera from ''Acetobacteraceae'' make up the acetic acid bacteria. History ''Acetobacteraceae'' was originally proposed as a family for ''Acetobacter'' and ''Gluconobacter'' based on rRNA and DNA–DNA hybridization comparisons in 1980. Genera Accepted Genera The following genera have been effectively and validly published: * ''Acetobacter'' Beijerinck 1898 (Approved Lists 1980) * '' Acidibrevibacterium'' Muhadesi ''et al''. 2019 * '' Acidicaldus'' Johnson ''et al''. 2006 * ''Acidiphilium'' Harrison 1981 * '' Acidisoma'' Belova ''et al''. 2009 * '' Acidisphaera'' Hiraishi ''et al''. 2000 * '' Acidocella'' Kishimoto ''et al''. 1996 * ''Acidomonas'' Urakami ''et al''. 1989 * '' Amey ...

Roseomonas
''Roseomonas'' is a genus of Gram negative bacteria. The cells are coccoid rods when viewed microscopically. Certain species are known to be opportunistic infections for humans. Background The first species isolated had pink colonies when grown on agar, which led to the naming of the genus (from Latin ''roseus'', pink).Rihs, J.D., Brenner, D.J., Weaver, R.E., Steigerwalt, A.G., Hollis, D.G. and Yu, V.L., 1993. Roseomonas, a new genus associated with bacteremia and other human infections. Journal of Clinical Microbiology, 31(12), pp.3275-3283. "''Roseomonas'' species have been isolated frequently from blood, wounds, exudates, abscesses and genitourinary specimens," and have been isolated from environmental sources. ''Roseomonas'' can cause bacteremia in humans, especially in immunocompromised patients. While uncommon, the reported rate of ''Roseomonas'' infection may be lower due to difficulty in detection of the bacteria in clinical settings. The first species of ''Roseomonas'' ...

Gram Negative
The gram (originally gramme; SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one one thousandth of a kilogram. Originally defined as of 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre melting ice", the defining temperature (~0 °C) was later changed to 4 °C, the temperature of maximum density of water. However, by the late 19th century, there was an effort to make the Base unit (measurement), base unit the kilogram and the gram a derived unit. In 1960, the new International System of Units defined a ''gram'' as one one-thousandth of a kilogram (i.e., one gram is Scientific notation, 1×10−3 kg). The kilogram, as of 2019, is defined by the International Bureau of Weights and Measures from the fixed numerical value of the Planck constant (), which is kg⋅m2⋅s−1.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
