Taxonomy

Group: dsDNA

Structure

Viruses in Spounalikevirus are non-enveloped, with head-tail geometries, and T=16 symmetry. The diameter is around 108 nm, with a length of 140 nm. Genomes are linear, around 145kb in length. The genome codes for 200 proteins.

Life Cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion.

Taxonomic history

  • Bacillus phage SP8 was assigned to the family Myoviridae in 1995.
  • Bacillus phage SPO1 was assigned to the genus SPO1-like phages in 1996 as type species.
  • Myoviridae were assigned to the order Caudovirales in 1998
  • SPO1-like phages were renamed SPO1-like viruses in 1999
  • Bacillus phage SP8 was merged into Bacillus phage SPO1 in 1999 (as type species) of SPO1-like viruses.
  • SPO1-like viruses were assigned to the sub-family Spounavirinae (of Caudovirales) in 2011.
  • SPO1-like viruses were renamed Spounalikevirus in 2012
