International audience. Guttaviridae is a family of enveloped viruses infecting hyperthermophilic archaea. The virions are ovoid or droplet-shaped, with a diameter of 55-80 nm and a length of 75-130 nm. The genome is a circular dsDNA molecule of around 14-20 kbp. The droplet-shaped morphology is unprecedented among viruses of bacteria and eukaryotes and represents a group of archaea-specific virion morphotypes. The family includes two genera, Alphaguttavirus and Betaguttavirus, each with a single species. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of Guttaviridae, which is available at www.ictv.global/report/guttaviridae.
