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.
Bicaudaviridae is a family of hyperthermophilic archaeal viruses.Members of the genus Acidianus serve as natural hosts. There is only one genus, Bicaudavirus, and one species, Acidianus two-tailed virus, in this family.
Acidianus rod-shaped virus 1 (ARV1), scientific name Itarudivurs ARV1, is an archaeal virus and the sole species in the genus Itarudivirus. [2] Its only known host is Acidianus sp. Acii26 . [ 3 ]
Bottigliavirus is the only genus in the family Ampullaviridae and contains 3 species. [3] [4] Ampullaviridae infect archaea of the genus Acidianus. [5]The name of the family and genus is derived from the Latin word for bottle, ampulla, due to the virions having the shape of a bottle.
When developing vaccines for viruses, the emphasis is on attenuating the virus, or decreasing its virulence, in a given host. Sometimes it is useful to employ serial passage to increase the virulence of a virus. Usually, when serial passage is performed in a species, the result is a virus that is more virulent to that species. [5]
