Pathogen CharacteristicsTop of page
African horse sickness virus (AHSV) is a member of the family Reoviridae of the genus Orbivirus. There are 9 antigenically distinct serotypes of AHSV identified by virus neutralization, but some cross-reaction has been observed between 1 and 2, 3 and 7, 5 and 8, and 6 and 9. No cross-reactions with other known orbiviruses have been observed (OIE, 2013).
Both in morphology and molecular constituents, AHSV particles are comparable to those of bluetongue virus (BTV), the prototype virus of the Orbivirus genus. AHSV has seven structural proteins (VP1-7). The outer capsid is composed of VP2 and VP5. The inner capsid, or core, is composed of two major proteins, VP3 and VP7, and three minor proteins, VP1, VP4 and VP6. Within the core is the virus genome. This genome consists of 10 double-stranded RNA segments of different sizes, three large (L1-L3), three medium (M4-M6) and four small (S7-S10). In addition to the seven structural proteins that are coded by seven of the RNA species, four non-structural proteins (NS1, NS2, NS3 and NS3A) are coded by three RNA segments (Roy et al., 1994).
Infection with African horse sickness virus is the list of diseases notifiable to the World Organisation for Animal Health (OIE). For more information, see the website www.oie.int.
