Virus classification
Group: Group II (ssDNA)
Family: Inoviridae

Inoviridae is a family of viruses. Bacteria serve as natural hosts. There are currently 43 species in this family, divided among 2 genera.[1][2]


Group: ssDNA



Viruses in Inoviridae are non-enveloped, with rod of filaments geometries. The diameter is around 7 nm, with a length of 2000 nm. Genomes are circular, around 8kb in length. The genome codes for 4 to 10 proteins.[1]

Life Cycle[edit]

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 viral extrusion. Bacteria serve as the natural host.[1]
