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.

Life cycle

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