title: A survey of cattle for antibodies against bluetongue and epizootic hemorrhagic disease of deer viruses in British Columbia and southwestern Alberta in 1987.
abstract: In 1987 a serological survey of cattle for antibodies (Ab) to bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV) was undertaken in British Columbia and southwestern Alberta after infection with the viruses was diagnosed in wild and domestic ruminants in the Okanagan Valley. Of 4610 cattle tested, five had Ab only to BTV, 125 had antibodies only to EHDV and 16 had Ab to both viruses. The Ab were identified as specific for BTV type 11 (BT-11) or EHDV type 2 (EHDV-2). All but one of the seropositive cattle originated in the Okanagan Valley of British Columbia. The remaining one seropositive animal which had Ab to EHDV-2 was pastured with a bull purchased from the Okanagan Valley.
