Members of this genus infect Shewanella putrefaciens. The non-redundant part of the genomes of viruses in this genus is, on average, 54.56 kbp (50.0 %G+C), with 68 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.
