Family: Herelleviridae

Genus: Tybeckvirus

Distinguishing features

Known members have genomes of about 136.5 kbp with 188–191 predicted protein coding sequences and 1–11 tRNAs. No terminal repeats have been located (Feyereisen et al., 2019). All known members of the genus infect Lactobacillus brevis.

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.
