The single member of this genus (Escherichia phage vB_EcoM-4HA13) infects Escherichia coli. The unique sequence of the genome of this phage is 52.40 kbp (42.8 % G+C), containing terminal repeats of about 3 kbp, with 81 protein coding gene.
Species demarcation criteria
There is only one species in the genus. Members of this species are more than 95% identical in genome nucleotide sequence, including the terminal repeat region. Viruses with genomes that differ by more than 5% will be assigned to different species.
