چکیده

The New Jersey strain of EHD virus has been propagated in newborn Swiss mice by the intracerebral route and is regularly lethal beyond the first serial mouse passage. A complement-fixing antigen prepared from the brains of infected mice reacts positively with the sera of deer recovered from infection with either the New Jersey or South Dakota strain of virus, but not with the serum of normal deer. The mouse-passaged virus induced an inapparent infection in an experimental deer. The virus can also be grown serially in HeLa cell culture and induces a characteristic cytopathic effect. It is neutralizable in such cultures to high titer by the sera of deer recovered from EHD (New Jersey strain) and to lower titer by the serum of a deer recovered from EHD (South Dakota strain). Normal deer serum does not neutralize the virus in tissue culture. The HeLa cell-passaged virus induced typical lethal EHD in an experimental deer and virus could be recovered from most of the tissues of this animal in HeLa cell culture. An unexplained prozone of inhibition of cytopathogenicity at low dilutions was observed in cultures of some of the organs. The fact that EHD virus exhibited a limited sensitivity to sodium desoxycholate suggests that it may belong in the arbor virus group.

The Attenuation of the Virus of Epizootic Hemorrhagic Disease of Deer by Its Serial Passage in the Brains of Newborn Mice

Serial passage through the brains of newborn mice markedly attenuates the New Jersey strain of EHD virus. Deer inoculated with this attenuated virus show no clinical evidence of illness, but do develop virus-neutralizing antibodies in their sera. They also become solidly immune to infection with the regularly fatal unattenuated virus.

Epizootic hemorrhagic disease is an important disease of cervids, especially white-tailed deer. The causative virus is widespread among wild cervids in North America, where white-tailed deer are endemic, and periodically causes serious epidemics in wild and/or captive populations. Sporadic clinical cases and outbreaks have also been reported in other cervids, cattle, bison, yaks and other anima...

Genomic Sequences of Epizootic Hemorrhagic Disease Viruses Isolated from Florida White-Tailed Deer

Epizootic hemorrhagic disease virus (EHDV) serotypes 1 and 2 were isolated from Florida white-tailed deer in 2015 and 2016, respectively, and their genomes were completely sequenced. To our knowledge, these are the first full genome sequences for EHDV-1 and -2 from Florida.

Serologic survey of selected pathogens in white-tailed and mule deer in western Nebraska.

Exposure of free-ranging white-tailed deer (Odocoileus virginianus) and mule deer (Odocoileus hemionus) in western Nebraska to selected livestock pathogens was determined by serology and attempted virus isolation. Antibodies to bluetongue virus, epizootic hemorrhagic disease virus, and bovine respiratory syncytial virus were present in both species of deer. No serologic reactors to Brucella or ...
