Acidianus two-tailed virus |
|
Bicaudaviridae is a family of viruses. This family currently has a single genus (Bicaudavirus). This genus has a two known species - Acidianus two-tailed virus and Sulfolobus virus STSV1.
History
This family was first described in 2005.[1][2]
The name is derived from the Latin word 'bi' and 'cauda' meaning 'two-tail'.
Virology
The virons are lemon shaped with two tails - one at either end of a central core. The tails develop outside the host - the only known example of morphological change in a viron outside of its host. The tails terminate in anchor-like structures.
The genome is circular double-stranded DNA of 62 kilobases encoding 72 open reading frames.
This family may have either a lytic or a lysogenic life cycle.
The hosts of this family are species in the genera Acidianus and Sulfolobus.
