''Lambdatorquevirus'' is a genus of
viruses
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.

Structure
Viruses in ''Lambdatorquevirus'' are non-enveloped, with icosahedral geometries, and T=1 symmetry. The diameter is around 19-27 nm. Genomes are circular, around 2.1kb in length. The genome has 2 open reading frames.

Life cycle
Viral replication is nuclear. Entry into the host cell is achieved by penetration into the host cell. Replication follows the ssDNA rolling circle model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear pore export. Sea lions serve as the natural host.[
