Derivation of names

Caeruleovirus: derived by association with the name of one of the member species, Bacillus virus Deepblue, caerulean being a shade of blue.

Species demarcation criteria

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