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

Vírus (do latim virus, "veneno" ou "toxina") são pequenos agentes infecciosos, a maioria com 20-300 nm de diâmetro, apesar de existirem vírus ɡiɡantes de (0,6–1,5 µm), que apresentam genoma constituído de uma ou várias moléculas de ácido nucleico (DNA ou RNA), as quais possuem a forma de fita simples ou dupla. Os ácidos nucleicos dos vírus geralmente apresentam-se revestidos por um envoltório proteico formado por uma ou várias proteínas, que pode ainda ser revestido por um complexo envelope formado por uma bicamada lipídica. As partículas virais são estruturas extremamente pequenas, submicroscópicas. A maioria dos vírus apresenta tamanhos diminutos, que estão além dos limites de resolução dos microscópios ópticos, sendo comum para a sua visualização o uso de microscópios eletrônicos. Vírus são estruturas simples, se comparados a células, e não são considerados organismos, pois não possuem organelas ou ribossomos, e não apresentam todo o potencial bioquímico (enzimas) necessário à produção de sua própria energia metabólica. Eles são considerados parasitas intracelulares obrigatórios (característica que os impede de serem considerados seres vivos), pois dependem de células para se multiplicarem. Além disso, diferentemente dos organismos vivos, os vírus são incapazes de crescer em tamanho e de se dividir. A partir das células hospedeiras, os vírus obtêm: aminoácidos e nucleotídeos; maquinaria de síntese de proteínas (ribossomos) e energia metabólica (ATP). Fora do ambiente intracelular, os vírus são inertes. Porém, uma vez dentro da célula, a capacidade de replicação dos vírus é surpreendente: um único vírus é capaz de multiplicar, em poucas horas, milhares de novos vírus. Os vírus são capazes de infectar seres vivos de todos os domínios (Eukarya, Archaea e Bactéria). Desta maneira, os vírus representam a maior diversidade biológica do planeta, sendo mais diversos que bactérias, plantas, fungos e animais juntos. Quase 200 mil tipos diferentes de vírus se espalham nos oceanos do mundo, de acordo com um estudo. A contagem de 2019 é 12 vezes maior do que o censo anterior de vírus marinhos registrado em 2016. Existem, individualmente, cerca de dez nonilhões (10³¹) de vírus no planeta Terra, uma quantidade cem milhões de vezes maior que o número de estrelas no universo observável.
