How to pronounce orthobunyavirus


Epidemiology

The genus is most diverse in Africa, Australia and Oceania, but occurs almost worldwide. Most orthobunyavirus species are transmitted by gnats and cause diseases of cattle. The California encephalitis virus, the La Crosse virus and the Jamestown Canyon virus are North American species that cause encephalitis in humans.

Virology

  • The type species is the Bunyamwera Virus.
  • The virus is spherical, diameter 80 nm to 120 nm, and comprises three single stranded RNA molecules encapsulated in a ribonucleocapsid.
  • The three RNAs are described as S, M and L (for Small, Medium and Large) and are circa 1kb (kilobases), 4.5kb and 6.5kb in length
  • The S RNA encodes the Nucleocapsid protein (N protein) and a non structural protein (NS Protein).
  • The M RNA encodes a polyprotein which is cleaved by host protease into Gn, NSm and Gc proteins.
  • The L RNA encodes the viral RNA dependent RNA Polymerase or L Protein

    • Serogroups

    The taxonomy remains somewhat fluid as relatively few viral genomes in this genus have been sequenced. Several of the viruses listed have been shown to be recombinants of other viruses and may be reclassified.

    18 serogroups have been recognized on the basis of the results of cross-hemagglutination inhibition and antibody neutralization relationships. Another - Wyeomyia - has since been recognised. Several viruses have not yet been classified into one of the serogroups.

    The Simbu serogroup is the largest and contains at least 25 members. There are at least 13 members in the Group C serogroup.

    Medically important viruses belong to the Bwamba, Bunyamwera, California, Group C and Simbu serogroups.
