Structure

Tibrovirions are enveloped, with bullet shaped geometries. Tibrovirus genomes are linear, around 13.2 kb in length. The genome codes for 8 proteins.[1]

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral G glycoproteins to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the negative stranded RNA virus replication model. Negative stranded RNA virus transcription, using polymerase stuttering is the method of transcription. The virus exits the host cell by budding, and tubule-guided viral movement. Cattle and water buffalo serve as the natural host.[1]
