Muscavirus
Muscavirus is a genus of viruses, in the family Hytrosaviridae.[1] The fly Musca domestica is the natural host. There is currently only one species in this genus: the type species Musca hytrosavirus. Diseases associated with this genus include: salivary gland hypertrophy, and complete sterility of infected female flies by inhibiting eggs development.[2][3]

Structure
Viruses in the genus Muscavirus are enveloped, with rod-shaped geometries. The diameter is around 50 nm. Genomes are circular, around 124kb in length. The genome has 108 open reading frames.[2][3]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |

| Muscavirus | Rod-shaped | Enveloped | Circular | Monopartite |
Life cycle
Viral replication is nuclear. DNA-templated transcription is the method of transcription. Musca domestica serve as the natural host. Transmission routes are parental and contamination.[2][3]

| Muscavirus | Insects: house flies | Epithelium: secretory salivary glands; ovarioles; gonads | Contact: food; horizontal; vertical | Budding; horizontal; vertical | Nucleus | Nucleus | Contact: food; horizontal; vertical |
gollark: Thing is, generally working on things gets easier when they are not powered on and doing things.
gollark: But interacting with a running brain isn't?
gollark: More room for error.
gollark: It's a more complicated process interacting with a running brain.
gollark: I don't think so.
