Guttaviridae is a family of viruses. Archaea serve as natural hosts.[1][2] The name is derived from the Latin gutta, meaning 'droplet'.[3][4][5] The family contains one genus, Alphaguttavirus, which contains one species: Aeropyrum pernix ovoid virus 1 (Betaguttavirus kodakarajimaense).[6]

Taxonomy

The family currently contains one genera and species:[6][7]

  • Betaguttavirus
    • Aeropyrum pernix ovoid virus 1 (Betaguttavirus kodakarajimaense)

Genus Alphaguttavirus and species Sulfolobus newzealandicus droplet-shaped virus were removed in ICTV version 2021.[8]

Structure

Viruses in the family Guttaviridae are enveloped. The diameter is around 55–80 nm, with a length of 75–130 nm. Genomes are circular double-stranded DNA around 14 kilobases in length.[2][3] Virions are ovoid or droplet-shaped and covered with globular subunits.[2]

Life cycle

DNA-templated transcription is the method of transcription. Archaea serve as the natural host.[2][3]
