Abolishment of morphology-based taxa and change to binomial species names: 2022 taxonomy update of the ictv bacterial viruses subcommittee

HIGHLIGHTS

SUMMARY

    Abolishment of the families Myoviridae, Podoviridae, and Siphoviridae and the order Caudovirales The most drastic change in phage classification officialised with this release is the abolishment of the morphology-based families Myoviridae, Podoviridae, and Siphoviridae and the removal of the order Caudovirales, which is replaced by the class Caudoviricetes to group all tailed bacterial and archaeal viruses with icosahedral capsids and a doublestranded DNA genome. While this leaves some taxa as "unclassified" at the levels of family and order within the class Caudoviricetes (summarised in Supplementary Table S1), it allows for the creation of . . .
