Up to now there is only one species of this genus known (Cryptobacterium curtum ''Cryptobacterium curtum'' is a Gram-positive anaerobic rod bacteria isolated from human mouths.

Cryptobacterium Curtum
''Cryptobacterium curtum'' is a Gram-positive anaerobic rod bacteria isolated from human mouths. Description ''Cryptobacterium curtum'' are Gram-positive, obligately anaerobic, non-spore-forming, and rod-shaped bacteria. ''C. curtum'' has been isolated from a periodontal pocket sample of an adult patient and from necrotic dental pulp, respectively. ''C. curtum'' can also be isolated from human oral and dental infections like pulpal inflammations, advanced caries, dental abscesses or periodontitis. While ''C. curtum'' does not appear to be present in the normal microflora, the nearly double in population size when periodontitis is present. The cells are very short and can occur singly or in masses. These cells are inert in most biochemical tests. They do not hydrolyze starch or aesculin. They cannot reduce nitrate nor do they grow in the presence or absence of carbohydrates. ''C. curtum'' also had negative results for indole, catalase, and urease tests. Genome ...

Coriobacteriia
The ''Coriobacteriia'' are a class of Gram-positive bacteria within the Actinomycetota phylum.Ludwig, W., Euzéby, J., Schumann, P., Busse, H. J., Trujillo, M. E.,Kämpfer, P. & Whitman, W. B. (2012).

Springer-:Berlin Heidelberg Species within this group are nonsporulating, strict or facultative anaerobes that are capable of thriving in a diverse set of ecological niches. '' Gordonibacter'' species are the only members capable of motility by means of flagella within the class. Several species within the ''Coriobacteriia'' class have been implicated with human diseases that range in severity. '' Atopobium'', '' Olsenella'', and ''Cryptobacterium'' species have resp ...

Eggerthellales
The ''Eggerthellaceae'' are a family of Gram-positive, rod- or coccus-shaped Actinomycetota. It is the sole family within the order ''Eggerthellales.'' The name ''Eggerthellaceae'' is derived from the Latin term ''Eggerthella,'' referring to the type genus of the family and the suffix "-ceae," an ending used to denote a family. Together, ''Eggerthellaceae'' refers to a family whose nomenclatural type is the genus ''Eggerthella''. Biochemical characteristics and molecular signatures Members of this family are mostly anaerobic, non-motile (with the exception of some ''Gordonibacter'' and ''Senegalimassilia'' species that exhibit motility), asaccharolytic and do not form spores. ''Eggerthellaceae'' species are commonly isolated from human and animal faeces and other human sources such as the colon, vagina, oral cavity and blood. Some species have also been isolated from human samples of periodontal or endodontic infections, Crohn's disease and severe blood bacteremia. The G+C co ...

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 relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinomycetota
The ''Actinomycetota'' (or ''Actinobacteria'') are a phylum of all gram-positive bacteria. They can be terrestrial or aquatic. They are of great economic importance to humans because agriculture and forests depend on their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up anew by plants. While this role is also played by fungi, ''Actinomycetota'' are much smaller and likely do not occupy the same ecological niche. In this role the colonies often grow extensive mycelia, like a fungus would, and the name of an important order of the phylum, '' Actinomycetales'' (the actinomycetes), reflects that they were long believed to be fungi. Some soil actinomycetota (such as ''Frankia'') live symbiotically with the plants whose roots pervade the soil, fixing nitrogen for the plants in exchange for access to some of the plant's saccharides. Other species, such as many members of the genus '' Mycobacterium'', ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Monotypic Bacteria Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...
