Densovirus
''Ambidensovirus'' was a genus of viruses in the subfamily ''Densovirinae ''Densovirinae'' is a subfamily of single-stranded DNA viruses in the family ''Parvoviridae''. The subfamily has 11 recognized genera and 21 species. Densoviruses are known to infect members of insect orders ''Blattodea'', ''Diptera'', ''Hemipte ...''. In 2019, the genus was split into the following six genera, all of which still contain the name ''ambidensovirus'' and which are assigned to the same subfamily: * '' Aquambidensovirus'' * '' Blattambidensovirus'' * '' Hemiambidensovirus'' * '' Pefuambidensovirus'' * '' Protoambidensovirus'' * '' Scindoambidensovirus'' References {{Reflist Obsolete virus taxa ...

Densovirinae
''Densovirinae'' is a subfamily of single-stranded DNA viruses in the family ''Parvoviridae''. The subfamily has 11 recognized genera and 21 species. Densoviruses are known to infect members of insect orders ''Blattodea'', ''Diptera'', ''Hemiptera'', ''Hymenoptera'', ''Lepidoptera'', and ''Orthoptera'', while some viruses infect and multiply in crustaceans such as shrimp or crayfish, or sea stars from phylum Echinodermata. Virology Densoviruses are small (18–26 nanometers in diameter) and non enveloped. Virions are icosahedral in shape with triangulation number (T) = 1. There are 60 copies of the coat protein in the virion. Each copy has a shape described as a "quadrilateral 'kite-shaped' wedge", and the appearance of the surface is rough with many small projections. Virions do not appear to contain lipids. Genomes are non-segmented, about 4–6 kilobases in length and usually contain two or three open reading frames. The 5' open reading frame encodes two nonstructural protein ...

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 ...

Virus
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or ''virions'', consisting of (i) the genetic material, i. ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...
