(BTV) arthropod borne viral disease
of wild and domestic ruminants. Infection with bluetongue virus is common
worldwide but is usually subclinical or mild in most ruminants. Bluetonge
virus is the type-species of the genus Orbivirus. There are 24 serotypes
wordwide. Only 5 serotypes have been reported in the USA. In the USA,
the principal biologic vector is Culicoides variipennis sonorensis, which limits
distribution of the virus to southern and western regions. The pathogenesis
of bluetongue in cattle differs from that in sheep and is based on immediate IgE
hypersensitivity reactions. A serlogic response in ruminants can be detected
7-14 days after infection and is generally lifelong. Current reconnended serlogic
techniques for the detection of bluetongue virus antibody include agar gel immunodiffusion
and competitive ELISA. The latter is the test of choice and does not detect
cross-reacting antibody to other Orbivirus.
