Classification
Classification is a process related to categorization, the process in which ideas and objects are recognized, differentiated and understood. Classification is the grouping of related facts into classes. It may also refer to: Business, organizations, and economics * Classification of customers, for marketing (as in Master data management) or for profitability (e.g. by Activity-based costing) * Classified information, as in legal or government documentation * Job classification, as in job analysis * Standard Industrial Classification, economic activities Mathematics * Attribute-value system, a basic knowledge representation framework * Classification theorems in mathematics * Mathematical classification, grouping mathematical objects based on a property that all those objects share * Statistical classification, identifying to which of a set of categories a new observation belongs, on the basis of a training set of data Media * Classification (literature), a figure of speech li ...

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

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. ...

Baculoviridae
''Baculoviridae'' is a family of viruses. Arthropods, among the most studied being Lepidoptera, Hymenoptera and Diptera, serve as natural hosts. Currently, 85 species are placed in this family, assigned to four genera. Baculoviruses are known to infect insects, with over 600 host species having been described. Immature (larval) forms of lepidopteran species (moths and butterflies) are the most common hosts, but these viruses have also been found infecting sawflies, and mosquitoes. Although baculoviruses are capable of entering mammalian cells in culture, they are not known to be capable of replication in mammalian or other vertebrate animal cells. Starting in the 1940s, they were used and studied widely as biopesticides in crop fields. Baculoviruses contain a circular, double-stranded DNA (dsDNA) genome ranging from 80 to 180 kbp. Historical influence The earliest records of baculoviruses can be found in the literature from as early as the 16th century in reports of "wilting ...

Hytrosaviridae
''Hytrosaviridae'' is a family of double-stranded DNA viruses that infect insects.Abd-Alla A, Vlak J, Bergoin M, Maruniak J, Parker A, Burand J, Jehle J, Boucias D and Hytrosavirus Study Group of the ICTV (2009) ''Hytrosaviridae'': a proposal for classification and nomenclature of a new insect virus family. Arch Virol 154:909–918 The name is derived from ''Hytrosa'', sigla from the Greek ''Hypertrophia'' for 'hypertrophy' and 'sialoadenitis' for 'salivary gland inflammation.' Description The viruses in this family are non occluded, enveloped, rod-shaped virions measuring 500–1,000 nanometers (nm) in length and 50–80 nm in diameter. The virions contain a thin, dense central nucleocapsid that encases the DNA-protein core. The nucleocapsid core is surrounded by an amorphous proteinaceous tegument layer. The outer surface of the virions is studded with helical polymeric structure composed of virally-encoded and host-derived protein dimers. The virions contain at least 35 ...
