Guttaviridae is a family of viruses. Archaea serve as natural hosts. The name is derived from the Latin gutta, meaning 'droplet'.Mochizuki T, Sako Y, Prangishvili D (2011) Provirus induction in hyperthermophilic Archaea: Characterization of Aeropyrum pernix spindle-shaped virus 1 and Aeropyrum pernix ovoid virus 1. J Bacteriol 193(19):5412–5419Arnold HP, Ziese U and Zillig W (2000). SNDV, a novel virus of the extremely thermophilic and acidophilic archaeon Sulfolobus. Virology 272:409–16. The family contains one genus, Alphaguttavirus, which contains one species: Aeropyrum pernix ovoid virus 1 (Betaguttavirus kodakarajimaense).
Taxonomy The family currently contains one genera and species: Betaguttavirus Aeropyrum pernix ovoid virus 1 (Betaguttavirus kodakarajimaense)
Genus Alphaguttavirus and species Sulfolobus newzealandicus droplet-shaped virus were removed in ICTV version 2021.
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. Virions are ovoid or droplet-shaped and covered with globular subunits.
Life cycle DNA-templated transcription is the method of transcription. Archaea serve as the natural host.
