Glossinavirus is a genus of viruses, in the family Hytrosaviridae.[1] Glossina sp serve as natural hosts. There is only one species in this genus: Glossina pallidipes salivary gland hypertrophy virus (Glossinavirus glopallidipedis). Diseases associated with this genus include: partial sterility due to ovarian abnormalities or to testicular degeneration; can be asymptomatic in laboratory colonies.[2][3][4]

Structure

Viruses in the genus Glossinavirus are enveloped, with rod-shaped geometries. The diameter is around 50 nm. Genomes are circular, around 190kb in length. The genome has 160 open reading frames.[2][3]

Glossinavirus Rod-shaped Enveloped Circular Monopartite

Life cycle

Viral replication is nuclear. DNA-templated transcription is the method of transcription. Glossina species serve as the natural host. Transmission routes are parental.[2][3]
