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

病毒(拉丁語:virus)是僅能在生物體活細胞內複製繁衍的亞顯微病原體。它由核酸分子(DNA或RNA)与保护性外壳(蛋白质)构成的非细胞形态的类生物结构(bio-like structure),無法自行表現出生命現象,是介於生命体及非生命體之間的生化結構,既不是生物亦不是非生物,卻是寄生性自我複製物(self-replicator)。藉由感染機制侵入有機體後,这些简单的生化結構可以利用宿主的细胞系统自我复制,但无法独立生长和复制。病毒可以感染所有具有细胞结构的生命体。第一个已知的病毒是烟草花叶病毒,由马丁乌斯·贝杰林克于1899年发现并命名,迄今已有超过5000种类型的病毒得到鉴定。尽管学界对于病毒是否为一种生物仍有争议,病毒学(研究病毒的科学)总是被归为微生物学的分支。 病毒由两到三个成分组成:病毒都含有遺傳物質(RNA或DNA,只由蛋白质组成的朊毒體并不属于病毒);所有的病毒也都有由蛋白质形成的衣壳,用来包裹和保护其中的遗传物质;此外,部分病毒在到达细胞表面时能够形成脂质包膜环绕在外。病毒的形态各异,从简单的和到结构。病毒颗粒大约是细菌大小的千分之一。病毒的起源目前尚不清楚,不同的病毒可能起源于不同的机制:部分病毒可能起源于质粒(环状DNA,可以在细胞内复制并在细胞间转移),而其他某些则可能起源于细菌。 病毒有各式各樣的传播方式,不同类型的病毒采用不同的方法。例如,植物病毒可以透过以植物汁液为生的昆虫,如蚜虫,来在植物间进行传播;而动物病毒可以透过蚊虫叮咬而得以传播。这些携带病毒的生物体称为“载体”。流感病毒可以经由咳嗽和打喷嚏来传播;诺罗病毒则可以透过手足口途径来传播,即透过接触带有病毒的手、食物和水;輪狀病毒常常是透过接触受感染的儿童而直接传播的;此外,艾滋病毒则可以透过體液接触来传播。 并非所有的病毒都会导致疾病,因为许多病毒的复制并不会对受感染的器官产生明显的伤害。某些病毒,如艾滋病毒,可以与人体长时间共存,并且依然能保持感染性而不受到宿主免疫系统的影响,即“病毒持续感染”(viral persistence)。但在通常情况下,病毒感染能够引发免疫反應,消灭入侵的病毒。而这些免疫反应能够透过注射疫苗来产生,進而使接种疫苗的人或动物能够终生对相应的病毒免疫。像细菌这样的微生物也具有抵御病毒感染的机制,如限制修飾系統。抗生素对病毒没有任何作用,但用于治疗病毒感染的抗病毒药物已經研发出來。
