EHD has been found in some domestic ruminants and many species of deer including white-tailed deer, mule deer, elk, and pronghorn antelope. [4] Seropositive black-tailed deer , fallow deer , red deer , wapiti , and roe deer have also been found, which essentially means that they were exposed to the disease at some time in the past but may not ...
Chronic wasting disease (CWD), sometimes called zombie deer disease, is a transmissible spongiform encephalopathy (TSE) affecting deer.TSEs are a family of diseases thought to be caused by misfolded proteins called prions and include similar diseases such as BSE (mad cow disease) in cattle, Creutzfeldt–Jakob disease (CJD) in humans, and scrapie in sheep.

When infected deer congregate at an artificial feeding site, they could easily infect other deer that visit the same site. “It’ll facilitate more rapid transmission of disease,” says Fuda. 4.
Dirofilaria immitis, also known as heartworm or dog heartworm, is a parasitic roundworm that is a type of filarial worm, a small thread-like worm, and which causes dirofilariasis. It is spread from host to host through the bites of mosquitoes. Four genera of mosquitoes transmit dirofilariasis, Aedes, Culex, Anopheles, and Mansonia. [2]
From Latin dīrus 'fearful; ominous' + fīlum 'thread', Dirofilaria is a genus of nematodes of the superfamily Filarioidea.The first known description of Dirofilaria may have been by Italian nobleman Francesco Birago in 1626 in his Treatise on Hunting: “The dog generates two worms, which are half an arm’s length long and thicker than a finger and red like fire.”
Electron micrograph of Bluetongue virus, scale bar = 50 nm. Bluetongue (BT) disease is a noncontagious, arthropod-borne viral disease affecting ruminants, [1] primarily sheep and other domestic or wild ruminants, including cattle, yaks, [2] goats, buffalo, deer, dromedaries, and antelope. [3]
Female mango and deer flies require a blood meal for the production of a second batch of eggs. This batch is deposited near water, where the eggs hatch in 5–7 days. The larvae mature in water or soil, [ 5 ] where they feed on organic material such as decaying animal and vegetable products.
Humans are most often infected by tick/deer fly bite or through handling an infected animal. Ingesting infected water, soil, or food can also cause infection. Hunters are at a higher risk for this disease because of the potential of inhaling the bacteria during the skinning process.
