Emesvirus

Emesvirus is a genus of positive-strand RNA viruses, in the family "Fiersviridae". Enterobacteria serve as natural hosts. There are three species in this genus. In 2020, the genus was renamed from "Levivirus" to its current name.
Structure.
Viruses in "Emesvirus" are non-enveloped, with icosahedral and Spherical geometries, and T=3 symmetry. The capsid diameter is around 26 nm.
Genome.
Emesviruses have a positive-sense, single-stranded RNA genome. The genome is linear and non-segmented and around 3.5kb in length. The genome codes for four proteins, which are the coat, replicase, maturation, and lysis protein.
Life cycle.
Entry into the host cell is achieved by adsorption into the host cell. Replication follows the positive-strand RNA virus replication model. Positive-strand RNA virus transcription is the method of transcription. Translation takes place by suppression of termination. The virus exits the host cell by bacteria lysis. Enterobacteria serve as the natural host.
Taxonomy.
The genus "Emesvirus" has the following two species:
