Simplexvirus is a genus of viruses in the order Herpesvirales, in the family Orthoherpesviridae, in the subfamily Alphaherpesvirinae. Mammals, including humans, serve as natural hosts. Diseases associated with this genus include skin vesicles or mucosal ulcers, rarely encephalitis, and meningitis.[1][2]
Species
[edit]The genus contains the following species, listed by scientific name and followed by the common name of the species:[2][3]
- Simplexvirus atelinealpha1, Ateline herpesvirus 1

Structure
[edit]Viruses in Simplexvirus are enveloped, with icosahedral, spherical to pleomorphic, and round geometries, and T=16 symmetry. The diameter is around 150-200 nm. Genomes are linear and unsegmented, around 152kb in length.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Simplexvirus | Spherical pleomorphic | T=16 | Enveloped | Linear | Monopartite |
Lifecycle
[edit]Viral replication is nuclear, and is lysogenic. Entry into the host cell is achieved by attachment of the viral gB, gC, gD, and gH proteins to host receptors, which mediates endocytosis. Replication follows the dsDNA bidirectional replication model. DNA-templated transcription, with some alternative splicing mechanism, is the method of transcription. Translation takes place by leaky scanning. The virus exits the host cell by nuclear egress, budding, and microtubular outwards viral transport. Human and mammals serve as the natural hosts. Transmission routes are sexual, contact, and saliva.[1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Simplexvirus | Humans; mammals | Epithelial mucosa | Cell receptor endocytosis | Budding | Nucleus | Nucleus | Saliva |
