An archaeal virus is a virus that infects and replicates in archaea, a domain of unicellular, prokaryotic organisms. Archaeal viruses, like their hosts, are found worldwide, including in extreme environments inhospitable to most life such as acidic hot springs , highly saline bodies of water, and at the bottom of the ocean.
The viral eukaryogenesis hypothesis depicts a model of eukaryotic evolution in which a virus, similar to a modern pox virus, evolved into a nucleus via gene acquisition from existing bacterial and archaeal species. [5] The lysogenic virus then became the information storage center for the cell, while the cell retained its capacities for gene ...
Virulence can also be transferred using a plasmid. The noun virulence (Latin noun virulentia) derives from the adjective virulent, meaning disease severity. [5] The word virulent derives from the Latin word virulentus, meaning "a poisoned wound" or "full of poison". [5] [6] The term virulence does not only apply to viruses.
A virus is a submicroscopic infectious agent that replicates only inside the ... Virulent, from Latin ... Other archaeal viruses resemble the tailed bacteriophages ...
Adnaviria is a realm of viruses that includes archaeal viruses that have a filamentous virion (i.e. body) and a linear, double-stranded DNA genome. [1] The genome exists in A-form and encodes a dimeric major capsid protein (MCP) that contains the SIRV2 fold, a type of alpha-helix bundle containing four helices.

A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea.

Often simply called an antiviral. A class of antimicrobial medication used specifically for treating diseases caused by viral infections rather than ones caused by bacteria or other infectious agents. Unlike most antibiotics, antivirals typically do not destroy their target viruses but instead inhibit their development. They are distinct from virucides. assembly The construction of the virus ...
