Abstract

This article summarises the activities of the Bacterial Viruses Subcommittee of the International Committee on Taxonomy of Viruses for the period of March 2021-March 2022. We provide an overview of the new taxa proposed in 2021, approved by the Executive Committee, and ratified by vote in 2022. Significant changes to the taxonomy of bacterial viruses were introduced: the paraphyletic morphological families Podoviridae, Siphoviridae, and Myoviridae as well as the order Caudovirales were abolished, and a binomial system of nomenclature for species was established. In addition, one order, 22 families, 30 subfamilies, 321 genera, and 862 species were newly created, promoted, or moved.

Figures

**Fig. 1**
Cladogram depicting the taxonomic structure of the order *Caudoviricetes*. New bacterial and archaeal virus families created in 2021 are highlighted in green or blue, respectively, and those abolished are in red. Numbers of subfamilies, genera, and species are depicted as histograms adjacent to each family. Numbers in parentheses indicate changes recorded from ratified taxonomic proposals. Subfamilies and genera moved from the abolished families *Myoviridae*, *Podoviridae*, and *Siphoviridae* are detailed in Supplementary Table S1.
