OverviewAI-generated

A virus is a taxon within the parent taxon Biota, classified at the domain rank. It is a subclass of microorganism and pathogen, possessing a viral capsid as a part. The organism is studied by virology and exhibits characteristics such as a viral life cycle, scientific name, strain, and genetic variant. It has uses including virovory and causes effects like viral infectious disease and viral pneumonia.

The subject is distinct from computer viruses. It is the focus of the Commons category "Viruses" and the topic category Category:Viruses. In the World Register of Marine Species, the status is accepted at the Kingdom rank, with habitats including marine, brackish, and freshwater environments. The iNaturalist database lists the rank as species, with the common name Rose rosette disease, and records 3,876 observations.

PubMed contains 1,612,665 records for the query "virus." The Vinony graph indicates the topic is referenced by 4,653 other encyclopedia articles. iDigBio records show 56 media items from institutions CDA and CUP in the United States. The NCI Thesaurus ID is C14283.

A virus is a small infectious agent that can replicate only inside the living cells of an organism. Viruses can infect all types of organisms, from animals and plants to bacteria and archaea (Koonin et al. 2006). 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, about 5,000 viruses have been described in detail(Dimmock et al. 2006), although there are millions of different types (Breitbart & Rohwer 2005). Viruses are found in almost every ecosystem on Earth and are the most abundant type of biological entity (Edwards & Rohwer 2005, Lawrence et al. 2009). The study of viruses is known as virology, a sub-speciality of microbiology. Virus particles (known as virions) consist of two or three parts: the genetic material made from either DNA or RNA, long molecules that carry genetic information; a protein coat that protects these genes; and in some cases an envelope of lipids that surrounds the protein coat when they are outside a cell. The shapes of viruses range from simple helical and icosahedral forms to more complex structures. The average virus is

Un virus est un agent infectieux nécessitant un hôte, souvent une cellule, dont les constituants et le métabolisme déclenchent la réplication. Le nom virus a été emprunté au XVIe siècle par Ambroise Paré au latin vīrus, ī, n. (« venin, poison, proprement suc des plantes »). La science des virus est la virologie, et ses experts sont des virologues ou virologistes. On considère de plus en plus les virus comme faisant partie des acaryotes. Ils changent de forme durant leur cycle, passant par deux stades : 1. * Une phase extracellulaire sous forme de particule virale. Ils sont alors des objets particulaires, infectieux, constitués au minimum d'un acide nucléique, souvent englobé dans une capside de protéines ; 2. * Une phase intracellulaire : 3. * soit comme séquence virale sous forme dormante, 4. * soit en train de détourner activement la machinerie cellulaire au profit de sa réplication en parasitant tout ou partie du métabolisme de son hôte. Sous la forme intracellulaire (à l'intérieur de la cellule hôte), les virus sont des éléments génétiques qui peuvent s'intégrer à un chromosome du génome hôte (on parle alors de provirus ou de prophage) ou non (cas par exemple des usines à virions). Pour les humains, sur les environ 5 000 espèces décrites, seules 129 sont jugées pathogènes en 2018. Le débat sur la nature des virus repose sur des notions complexes et reste aujourd'hui ouvert. Selon de nombreuses définitions du vivant (entité matérielle réalisant les fonctions de relation, nutrition, reproduction), les virus ne sont pas des êtres vivants, mais d'autres définitions permettent de les considérer comme vivants.
