Members of the family Chaseviridae are lytic bacterial viruses infecting representatives of the bacterial class Gammaproteobacteria. Chaseviruses have a global distribution. Virions of members of this family have a myovirus morphology (icosahedral head with contractile tail). Genomes are dsDNA of 52-56 kbp with G+C content ranging from 39.3-52.5 %. Chaseviruses, like members of the family Autographiviridae, encode a large single subunit RNA polymerase, but unlike those viruses their promoter sequences have not yet been identified. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Chaseviridae, which is available at ictv.global/report/chaseviridae.
