Ostreavirus

Ostreavirus is a genus of viruses in the order Herpesvirales, and one of only two genera in the family Malacoherpesviridae. Molluscs serve as natural hosts. There is only one species described in this genus, Ostreid herpesvirus 1 (OsHV-1), commonly known as oyster herpesvirus. A disease associated with this genus is sporadic episodes of high mortality among larvae and juveniles.[1][2]

Acute viral necrosis virus, which affects scallops such as Chlamys farreri, appears to be a variant of Ostreid herpesvirus 1.[3]

Structure

Ostreavirus is enveloped, with spherical to pleomorphic geometry, and T=16 symmetry. The diameter is around 150-200 nm. The genome is linear and non-segmented, around 134kb in length.[1]

Life cycle

Viral replication is nuclear, and is lysogenic. DNA templated transcription is the method of transcription. Molluscs serve as the natural host.[1]

gollark: Good point!
gollark: Maybe your IDE is just bad.
gollark: However, Java bad, use Python.
gollark: `javac thing.java`, `java thing.class`, I think?
gollark: I checked and the person saying this said to use "dotpeek".
