ICTV Virus Taxonomy Profile: Spiraviridae

J Gen Virol. 2020 Mar;101(3):240-241. doi: 10.1099/jgv.0.001385.

Abstract

The family Spiraviridae includes viruses that replicate in hyperthermophilic archaea from the genus Aeropyrum. The non-enveloped, hollow, cylindrical virions are formed from a coiling fibre that consists of two intertwining halves of a single circular nucleoprotein filament. A short appendage protrudes from each end of the cylindrical virion. The genome is circular, positive-sense, single-stranded DNA of 24 893 nucleotides. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) report on the family Spiraviridae, which is available at ictv.global/report/spiraviridae.

Keywords: ICTV Report; Spiraviridae; taxonomy.
