Antibodies to Epizootic Hemorrhagic Disease Virus (EHDV) in Farmed and Wild Florida White-Tailed Deer (Odocoileus virginianus)   A Cauvin, ETN Dinh, JP Orange, RM Shuman… - Journal of Wildlife Diseases, 2019 

... Despite aggressive chemical vector control on the farm, we found higher seroprevalence and titers against the predominant EHDV serotype in farmed deer (in pens and the preserve) than in wild deer. The higher exposure to EHDV of farmed vs. wild deer may have been because of the higher densities of farmed vs. wild deer, the presence of exotic amplifying hosts such as elk (Cervus canadensis) in the preserve, or genetic factors that predisposed farmed deer to disease...

Bluetongue in white-tailed deer (Odocoileus virginianus) in Northeastern Mexico

J Martínez-Burnes, H Barrios-García, J Alva-Pérez… - Braz J Vet Pathol, 2017 [PDF]

... Two free ranging white-tailed deer (Odocoileus virginianus) in two licensed hunting ranches in Northern Mexico near the Texas border died unexpectedly. Postmortem and microscopic examinations revealed hemorrhagic lesions compatible with viral hemorrhagic disease (Reoviridae: Orbivirus).

A Mathematical Model to Analyze Spread of Hemorrhagic Disease in White-Tailed Deer Population  G Baygents, M Bani-Yaghoub - Journal of Applied Mathematics and Physics, 2017

... The model is employed to analyze the effects of deer migration on the HD spread. This is carried out in three steps. First, the conditions for existence and stability of the endemic and the disease free equilibria are established. Second, using the method of the Next Generation Matrix, the basic reproduction expression R0 is derived from the model. Third, using the R0 expression and its numerical simulations, it is illustrated that the severity of an HD outbreak is directly influenced by the migration rates of infected and susceptible deer ...

Testicular Lesions and Antler Abnormalities in Colorado, USA Mule Deer:  A Possible Role for Epizootic Hemorrhagic Disease Virus   KA Fox, B Diamond, F Sun, A Clavijo, L Sneed… - Journal of Wildlife Diseases, 2014

... Antler abnormalities of deer and other cervids often result from testicular lesions and decreased levels of testosterone, inhibiting normal cycles of antler growth. Affected males have antlers with retained velvet, numerous short, misshapen points (“cactus bucks”), and failure to shed these abnormal antlers annually. In Colorado, we observed a high occurrence of “cactus bucks” in mule deer ...  Although the role of EHDV infection remains unconfirmed, the association between testicular and epididymal lesions and presence of EHDV RNA in the affected tissues suggests that cactus buck antlers may be a sequela of EHDV infection....
