Subfamily: Spounavirinae


Subfamily: Spounavirinae

Distinguishing features

Members of this subfamily infect Bacillus sp. including B. cereus and B. subtilis. Virus genomes are of 132–146 kbp and have long terminal repeats.

Derivation of names

Spounavirinae – derived from Bacillus phage SPO1 (i.e. spo and una, meaning one), the first recognised isolate of this subfamily.

Genus demarcation criteria

The Spounavirinae genera are well-supported monophyletic clades in genome-based phylogenies and in (concatenated) marker gene phylogenies. Members of the genera share at least 60% nucleotide identity across the genome length. The genome organisation is conserved. Members of the same genus generally infect members of the same bacterial genus.
