The Leviviridae are a family of bacteriophages. These are small RNA viruses with linear, positive-sense, single-stranded RNA genomes that encode only four proteins. All phages of this family require bacterial pili to attach to and infect cells.
Taxonomy
The family has two genera, both of which currently have two known species.
- Family Leviviridae
- Genus Allolevivirus; type species: Enterobacteria phage Qβ
- Species: Enterobacteria phage FI and Enterobacteria phage Qβ
- Genus Levivirus; type species: Enterobacteria phage MS2
- Species: Enterobacteria phage BZ13 and Enterobacteria phage MS2
- Genus Allolevivirus; type species: Enterobacteria phage Qβ
Genome
The four proteins encoded are the coat, replicase, maturation and lysis proteins.
