''Spiromicrovirus'' 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. Viruses are found in almo ...

, in the family '' Microviridae'', in the subfamily '' Gokushovirinae''. Spiroplasma bacteria serve as natural hosts. There is only one species in this genus: ''Spiromicrovirus SpV4''.

Structure

Viruses in ''Spiromicrovirus'' are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 30 nm. Genomes are circular, around 6.1kb in length.

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by pilus-mediated adsorption into the host cell. Replication follows the ssDNA rolling circle model. DNA-templated transcription is the method of transcription. The virus exits the host cell by bacteria lysis. Spiroplasma bacteria serve as the natural host.
