Nudiviridae is a family of viruses, the nudiviruses. Insects and marine crustaceans serve as natural hosts. There are currently three species in this family, divided among 2 genera. Diseases associated with this family include: death in larvae, chronic disease in adults.[1][2]
Taxonomy
Group: dsDNA
Order: Unassigned
- Family: Nudiviridae
- Genus: Alphanudivirus
- Gryllus bimaculatus nudivirus
- Oryctes rhinoceros nudivirus
- Genus: Betanudivirus
- Heliothis zea nudivirus
Structure
Viruses in Nudiviridae are enveloped, with rod-shaped geometries. Genomes are circular.[1]
| Genus | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |
|---|---|---|---|---|---|
| Alphanudivirus | Rod-shaped | Enveloped | Circular | ||
| Betanudivirus | Rod-shaped | Enveloped | Circular |
Life Cycle
Viral replication is nuclear. DNA-templated transcription is the method of transcription. The virus exits the host cell by nuclear envelope breakdown, and nuclear pore export. Insects and marine crustaceans serve as the natural host. Transmission routes are parental and sexual.[1]
