ICTV Virus Taxonomy Profile: Turriviridae 2024

Abstract

The family Turriviridae includes viruses with a dsDNA genome of 16–17 kbp. Virions are spherical with a diameter of approximately 75 nm and comprise a host-derived internal lipid membrane surrounded by a proteinaceous capsid shell. Members of the family Turriviridae infect extremophilic archaea of the genera Sulfolobus and Saccharolobus. Viral infection results in cell lysis for Sulfolobus turreted icosahedral virus 1 infection but other members of the family can be temperate. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Turriviridae, which is available at ictv.global/report/turriviridae.
