Class: incertae sedis
Order: incertae sedis
Family: Globuloviridae
  • Globulovirus

Globuloviridae is a family of hyperthermophilic archaeal viruses. Crenarchaea of the genera Pyrobaculum and Thermoproteus serve as natural hosts. There are currently only two species in this family, Pyrobaculum spherical virus and Thermoproteus tenax spherical virus 1, included into a single genus, Globulovirus.[1][2]


Group: dsDNA



Virions in the Globuloviridae are spherical and enveloped. The diameter is around 100 nm. Genomes are linear dsDNA and non-segmented, around 20-30kb in length.[1][2]

Life cycle[edit]

Viral replication is cytoplasmic. DNA-templated transcription is the method of transcription. Pyrobaculum and Thermoproteus archaea serve as the natural host. Transmission routes are passive diffusion.[1]
