Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species: * ''Iteradensovirus incertum1'', Bat-associated densovirus 5 * ''Iteradensovirus incertum2'', Human CSF-associated densovirus * ''Iteradensovirus lepidopteran1'', Bombyx mori densovirus 1 * ''Iteradensovirus lepidopteran2'', Casphalia extranea densovirus * ''Iteradensovirus lepidopteran3'', Dendrolimus punctatus densovirus * ''Iteradensovirus lepidopteran4'', Papilio polyxenes densovirus * ''Iteradensovirus lepidopteran5'', Helicoverpa armigera densovirus


Structure

Viruses in ''Iteradensovirus'' are non-enveloped, with icosahedral and Round geometries, and T=1 symmetry. The diameter is around 21-22 nm. Genomes are linear, around 5kb in length.


Life cycle

Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the rolling-hairpin model. DNA templated transcription, with some alternative splicing mechanism is the method of transcription. Insects serve as the natural host.
