Bicaudaviridae is a family of viruses. Genus acidianus serve as natural hosts. There was only one genus (Bicaudavirus) and one species in this family: the type species Acidianus two-tailed virus.[1][2] until the Sulfolobus tengchongensis spindle-shaped virus 1 (STSV-1) was regarded to belong to this family also.[3]

Structure
Viruses in Bicaudaviridae are enveloped, with lemon-shaped geometries. Genomes are circular, around 62kb in length. The genome has 72 open reading frames.[1]
| Genus | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |
|---|---|---|---|---|---|
| Bicaudavirus | Lemon-shaped | Circular | Monopartite |
Life Cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Dna templated transcription is the method of transcription. Genus acidianus serve as the natural host. Transmission routes are passive diffusion.[1]

History
This family was first described by the team led by D. Prangishvili in 2005.[4][5]
The name is derived from the Latin word 'bi' and 'cauda' meaning 'two-tail'.
