Densovirinae
Densovirinae
Densovirinae (pronunciation: den-so-vi-ri-nae) is a subfamily of viruses in the family Parvoviridae.
Etymology
The name Densovirinae is derived from the Latin word 'densus', meaning 'dense', and 'virus', which is Latin for 'poison'. This is in reference to the high density of the virus particles.
Description
Densovirinae viruses are non-enveloped and have an icosahedral capsid, which is a characteristic of the Parvoviridae family. The genome is non-segmented, monopartite, and linear. The complete genome is 4000-6000 nucleotides long.
Life Cycle
The virus attaches to the host cell using a Viral protein and is then internalized by endocytosis. Replication follows the rolling-hairpin model, and transcription is nuclear. The virus exits the host cell by nuclear pore export, and viruses are then transmitted through a mechanism that is still not completely understood.
Diseases
Densovirinae viruses are known to cause diseases in invertebrates, particularly insects and crustaceans. The most well-known disease caused by this subfamily of viruses is the White Spot Syndrome in shrimp.
