Horse Pox
''Orthopoxvirus'' is a genus of viruses in the family ''Poxviridae'' and subfamily ''Chordopoxvirinae''. Vertebrates, including mammals and humans, and arthropods serve as natural hosts. There are 12 species in this genus. Diseases associated with this genus include smallpox, cowpox, horsepox, camelpox, and monkeypox. The most widely known member of the genus is ''Variola virus'', which causes smallpox. It was eradicated globally by 1977, through the use of ''Vaccinia virus'' as a vaccine. The most recently described species is the '' Alaskapox virus'', first isolated in 2015. Microbiology Structure Orthopoxviruses are enveloped with brick-shaped geometries and virion dimensions around 200 nm wide and 250 nm long. Genome Member viruses have linear DNA genomes around 170–250 kb in length. Lifecycle Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host glycosaminoglycans (GAGs), which mediate cellular ...

Taxonomy
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
