Subfamily: Nefertitivirinae

Genus: Phayathaivirus

Distinguishing features

Members of this genus infect Aeromonas veronii. The non-redundant part of the genomes of viruses in this genus is an average of 51 kbp (51.4 %G+C), with 64 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.
