Iteradensovirus is a genus of viruses in the subfamily Densovirinae of the family Parvoviridae.[1][2] Insects serve as natural hosts. There are seven species in this genus.[3][4]
Taxonomy
[edit]The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[4][5]
- 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
[edit]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.[3]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Iteradensovirus | Icosahedral | T=1 | Non-enveloped | Linear | None |
Life cycle
[edit]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.[3]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
