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.
Colorado tick fever is probably the same disease that American pioneers referred to as "mountain fever". [1] [2] Colorado tick fever virus (CTFV) infects haemopoietic cells, particularly erythrocytes, which explains how the virus is transmitted by ticks and also accounts for the incidence of transmission by blood transfusion.

The virus has a rod-shaped morphology with a width of 23 nanometers (nm) and a length of 900 nm. Three terminal fibers, 28 nm in length, have been observed on both ends of the virus. [3] The terminal fibers mediate attachment of the virus to type 4 pili abundantly present on the host cell surface. [4] [5]
A variant of the rustrela virus-- related to the wider-known rubella virus which causes a skin rash in humans -- called RusV was discovered in a female mountain lion in Douglas County, Colorado ...
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]
Stygiolobus rod-shaped virus (SRV), scientific name Azorudivirus SRV, is an archaeal virus and the sole species in the genus Azorudivirus. [2] Its only known host is Stygiolobus archaea . [ 3 ]
