VIRUS ISOLATION AND MOLECULAR DETECTION OF BLUETONGUE AND EPIZOOTIC HEMORRHAGIC DISEASE VIRUSES FROM NATURALLY INFECTED WHITE-TAILED DEER (ODOCOILEUS VIRGINIANUS).

Hemorrhagic disease in North America is caused by multiple serotypes of epizootic hemorrhagic disease virus (EHDV) and bluetongue virus (BTV). Diagnostic tests for detection of EHDV and BTV include virus isolation (VI), reverse transcriptase (RT)-PCR, and real-time RT-PCR (rRT-PCR). Our objective was to compare the diagnostic capabilities of three rRT-PCR protocols for detection of EHDV and BTV from naturally infected white-tailed deer (Odocoileus virginianus).

The First 10 Years (2006-15) of Epizootic Hemorrhagic Disease Virus Serotype 6 in the USA.

Epizootic hemorrhagic disease virus (EHDV) is a Culicoides biting midge-transmitted orbivirus (family Reoviridae) of wild and domestic ruminants and is an important pathogen of white-tailed deer (Odocoileus virginianus). Historically, only two serotypes, EHDV-1 and EHDV-2, have been known to be endemic in the US. However, in 2006, an exotic serotype (EHDV-6) was first detected in the US by a long-term passive surveillance system for EHDV and bluetongue viruses.
