Guttaviridae is a family of viruses. Archaea serve as natural hosts. There are two genera in this family, containing one species each.^[1]^[2] The name is derived from the Latin gutta, meaning 'droplet'.^[3]^[4]^[5]

Taxonomy

The family currently contains one genera and species:^[2]

Betaguttavirus
- Aeropyrum pernix ovoid virus 1

Genus Alphaguttavirus and species Sulfolobus newzealandicus droplet-shaped virus were removed in ICTV version 2021.^[6]

Structure

Viruses in the family Guttaviridae are enveloped. The diameter is around 70–95 nm, with a length of 110–185 nm. Genomes are circular, around 20kb in length.^[2]^[3] The virons consist of a coat, a core, a nucleocapsid, and projecting fibers at the pointed end. The surface of the virion has a beehive-like ribbed surface pattern with protrusions that are densely covered by a 'beard' of long fibers at its pointed end. The genome is extremely heavily methylated.^{[citation needed]}

Life cycle

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