Isolation and identification of bluetongue virus.
Bluetongue virus (BTV) is an arthropod-borne orbivirus that infects sheep, wild ruminants and occasionally cattle. Detection and specific identification of BTV is a multistep process. The first step involves the isolation of the virus from the animal's blood or other tissues, followed by inoculation of embryonating chicken eggs (ECE). After the virus has been amplified in ECE, it is passaged into BHK-21 cell culture for subsequent replication and identification. The virus is then amplified further and identified in microtiter plates by the immunoperoxidase assay using a group specific monoclonal antibody. Finally, the viral isolate is typed by a virus neutralization test.
