}}Betatetravirus is a genus of viruses, in the family Alphatetraviridae. Moths and butterflies serve as natural hosts. There are currently seven species in this genus including the type species Nudaurelia capensis beta virus. Infection outcome varies from unapparent to lethal.[1][2] TaxonomyGroup: ssRNA(+){{Collapsible list|title= Order: Unassigned|1={{Collapsible list| framestyle=border:none; padding:1.0em;|title=Family: Alphatetraviridae |1={{hidden begin|title=Genus: Betatetravirus}}
}} }}[2] StructureViruses in Betatetravirus are non-enveloped, with icosahedral geometries, and T=4 symmetry. The diameter is around 40 nm. Genomes are linear, around 6.5kb in length.[1]
Life cycleViral 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 ribosomal skipping. Moths and butterflies serve as the natural host. Transmission routes are oral.[1]
