Alphatetraviridae is a family of viruses. Moths and butterflies serve as natural hosts. There are two genera in the family. Infection outcome varies from unapparent to lethal.[1][2]
The following genera are assigned to the family:[2]
Structure
Viruses in Alphatetraviridae are non-enveloped, with icosahedral geometries, and T=4 symmetry. The diameter is around 40 nm. Genomes are linear and non-segmented, bipartite, around 6.5kb in length.[1]
