''Alphatetraviridae'' is a family of
viruses A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1 ...
. Moths and butterflies serve as natural hosts. There are two genera in the family. Infection outcome varies from unapparent to lethal.


Taxonomy

The following genera are assigned to the family: *'' Betatetravirus'' *'' Omegatetravirus''


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.


Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded rna virus transcription is the method of transcription. Translation takes place by leaky scanning, and ribosomal skipping. Moths and butterflies serve as the natural host. Transmission routes are oral.
