Globuloviridae is a family of hyperthermophilic archaeal viruses. Crenarchaea of the genera Pyrobaculum and Thermoproteus (both in Thermoproteaceae) serve as natural hosts. There are four species in this family, assigned to a single genus, Alphaglobulovirus.
The family contains one genus which contains four species:
Virions in the Globuloviridae are spherical and enveloped. The diameter is around 100 nm.
Genomes are linear dsDNA and non-segmented, around 20âÂÂ30kb in length.
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.
