Aeropyrum coil-shaped virus

Spiraviridae is a family of single stranded DNA viruses that infect archeae.[1]


This family was described in 2012.[1]

The species in this family have a positive sense single stranded DNA genome. The viron capsid is non enveloped, hollow and cylindrical. It composed of a coiling fiber which in turn consists of two intertwining halves of a single circular nucleoprotein.

Species in this family infect archaea.


There is one species in this family currently recognised.
