Subfamily: Cleopatravirinae

Genus: Fifivirus

Distinguishing features

Members of this genus infect Erwinia amylovora. The non-redundant part of the genomes of viruses in this genus is 53.56 kbp (50.0 %G+C), with 78 gene coding sequences; no tRNAs are encoded.

Species demarcation criteria

Members of the same species are more than 95% identical in genome nucleotide sequence, including the terminal repeat region. Viruses with genomes that differ by more than 5% are assigned to different species.
