Nudivirus
A nudivirus (family Nudiviridae) is a large, rod-shaped virus with a circular, double stranded DNA genome of 96–231 kb. The genome encodes 98 to 154 open reading frames. Virions are rod-shaped and when enveloped are up to 382×77 nm.
The word "nudivirus" comes from the Latin nudus, which means naked and virus, poison. Naked refers to the fact that, unlike baculoviruses, they are not occluded by cryoproteins.
