Aeropyrum pernix ovoid virus 1[1] Sulfolobus newzealandicus droplet-shaped virus

Guttavirus is a genus of dsDNA virus that infects the species of Archaea.[2]

The name is derived from the Latin gutta, meaning 'droplet'.


The virons consist of a coat, a core, a nucleocapsid, and projecting fibers at the pointed end. They are ovoid (droplet shaped), enveloped, 70-95 nm in diameter and 110–185 nm long. 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 circular non segmented double-stranded DNA about 20 kilobases in length. The genome is extremely heavily methylated.
