Fiersviridae is a family of positive-strand RNA viruses which infect prokaryotes.[1] Bacteria serve as the natural host.[2] They are small viruses with linear, positive-sense, single-stranded RNA genomes that encode four proteins. All phages of this family require bacterial pili to attach to and infect cells.[3] The family has 185 genera,[4] most discovered by metagenomics.[2] In 2020, the family was renamed from Leviviridae to its current name.[2][5]
