Phasmaviridae

Phasmaviridae is a family of viruses with negative stranded RNA genomes associated with insect hosts. They are a member of the order Bunyavirales.[1] Phasmaviruses were first discovered in phantom midges of the genus Chaoborus in 2014.[2]

Taxonomy

Five genera are currently recognized in this family.[1]

Ferak feravirus

Ferak feravirus, a member of the genus Feravirus, has been isolated in cell culture. The virion is enveloped and spherical with a diameter of 80–120 nanometers. The genome has three segments L (6.8 kilobases), M (4.2 kilobases) and S (1.5 kilobases). It encodes five proteins—the polymerase on the L segment, the p12G and the Gc-Gn protein on the M segment and the N and p12 proteins in the S segment.[3]

A Gn–Gc glycoprotein dimer binds to the cell receptor. The virus is endocytosed and escapes into the cytoplasm where it replicates. It is released from the cell by budding.[3]
