Tupavirus is a genus of viruses in the order Mononegavirales, in the family Rhabdoviridae. Birds serve as natural hosts. There are currently only two species in this genus, including the type species Durham virus.^[1]^[2]

Structure

Viruses in Tupavirus are enveloped, with bullet shaped geometries. These viruses are about 160 nm long. Genomes are linear, around 11.2kb in length. The genome codes for 7 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. Birds serve as the natural host.^[1]
