Serological evidence of epizootic hemorrhagic disease and serotypes of epizootic hemorrhagic disease virus in Pakistan

Acta Tropica
This study investigated seroprevalence and serotypes of Epizootic hemorrhagic disease virus (EHDV) in ruminants in North-Western Pakistan. A total of 616 serum samples were tested for the presence of antibodies against EHDV and neutralizing antibodies against 7 EHDV serotypes (EHDV-1, 2, 4, 5, 6, 7 and 8) using competitive ELISA and VNT, respectively ...

Epizootic hemorrhagic disease virus of deer: an electron microscopic study

Canadian Journal of Microbiology, 1970
A mouse brain adapted strain of epizootic hemorrhagic disease (EHD) virus of deer was studied by ultrathin section and negative contrast electron microscopy. In sections of infected BHK-21 cells and neurons of newborn mouse brains, aggregates of virus particles, some appearing to be lacking their outer coats, were observed within membrane-bound ...

Plaque Neutralization of Bluetongue Virus and Epizootic Hemorrhagic Disease Virus in BHK21 Cells

American Journal of Veterinary Research, 1976
SUMMARY Plaque assay and plaque neutralization of bluetongue virus and epizootic hemorrhagic disease virus were studied in baby hamster kidney (bhk21) cells grown under an overlay containing gum tragacanth. Tests were done in plastic panels, each with 24 wells, and variables were established for achieving reproducible results.

EXPERIMENTAL INFECTION IN NORTH AMERICAN ELK WITH EPIZOOTIC HEMORRHAGIC DISEASE VIRUS

Journal of Wildlife Diseases, 1973
Two elk (Cervus canadensis) were inoculated intravenously with epizootic hemorrhagic disease virus. No overt signs of disease were observed in the elk although one animal had a slight febrile response. A cell associated viremia was detected in both elk, which persisted in one animal for 30 days post-inoculation.

Review of epizootic hemorrhagic disease in cattle and a study defining seroprevalence of epizootic hemorrhagic disease virus serotype 2 in Texas cattle

The Bovine Practitioner, 2018
Epizootic hemorrhagic disease virus is an orbivirus transmitted by Culicoides spp. In North America, it is recognized as a major cause of disease affecting white-tailed deer, but it can impact other wildlife species as well as domestic cattle. Although minimal clinical disease had been noted in Texas, periodic outbreaks in other states caused Texas ...

Molecular and genetic comparisons of two serotypes of epizootic hemorrhagic disease of deer virus

American Journal of Veterinary Research, 1986
SUMMARY The virus-specific double-stranded genome RNA of 2 serotypes of epizootic hemorrhagic disease of deer virus (ehdv) was evaluated by use of coelectrophoresis in polyacrylamide and agarose gel systems. The molecular weights of virion RNA segments were 0.32 to 2.57 × 106 for ehdv-1 and 0.33 to 2.54 × 106 for ehdv-2. Seven of 10 double-stranded RNA

TRANSMISSION OF TWO STRAINS OF EPIZOOTIC HEMORRHAGIC DISEASE VIRUS IN DEER BY Culicoides variipennis

Journal of Wildlife Diseases, 1977
Two strains of epizootic hemorrhagic disease virus (EHDV), New Jersey (NJ) and Kentucky (KY), of deer were biologically transmitted between white-tailed deer, Odocoileus virginianus, by Culicoides variipennis. The KY strain, isolated from C. variipennis collected during an epizootic in deer, was identified as EHDV by serological tests.

Isolation and characterization of epizootic hemorrhagic disease virus from sheep and cattle in Colorado

American Journal of Veterinary Research, 1988
SUMMARY Epizootic hemorrhagic disease virus was isolated from cattle and sheep in northeastern Colorado during July and August 1984. The isolates were identified as serotype 2 by plaque-inhibition serotyping, genome electropherotyping, and protein analysis.

Development and statistic evaluation of a plaque assay for the virus of epizootic hemorrhagic disease of deer

Canadian Journal of Microbiology, 1970
A plaque assay system for the virus of epizootic hemorrhagic disease of deer in the WI-2 subline of BHK-21 cells is described. The system uses infection of the cells in suspension before growth as a monolayer under supplemented Leibovitz L-15 medium incorporating gum tragacanth. Crude cell lysates were initially used as a source of virus for the assay

Epizootic Hemorrhagic Disease Virus Titration

The titration of viruses onto susceptible cell lines is an important virological technique used to quantify infectious viral titers. It forms an integral component of epizootic hemorrhagic disease virus (EHDV) research, including estimating infectivity, calculating multiplicity of infection, and confirming virus propagation in cell culture.
