# ICTV Virus Taxonomy Profile: Turriviridae 2024

## TL;DR

This paper summarizes the taxonomy of Turriviridae, a virus family infecting archaea, with details on their structure and host range.

## Contribution

Provides an updated ICTV taxonomy profile for Turriviridae, highlighting their unique characteristics and host interactions.

## Key findings

- Turriviridae viruses have a dsDNA genome of 16–17 kbp and a spherical virion structure.
- They infect extremophilic archaea like Sulfolobus and Saccharolobus.
- Some Turriviridae members cause cell lysis, while others are temperate.

## 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.
