Wildlife agencies discourage such efforts, which cause harm to mule deer populations by spreading disease (such as tuberculosis and chronic wasting disease) when deer congregate for feed, disrupting migratory patterns, causing overpopulation of local mule deer populations, and causing habitat destruction from overbrowsing of shrubs and forbs ...
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.

After gastropod ingestion, moose or other deer may be hosts of the second- and third-stage worms. Moose resistance to P. tenuis is much lower than white-tailed deer, which results in a higher mortality rate. [9] Infected deer density, temperature, climate conditions, and length of transmission periods all affect transmission levels.
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 ...
The fibromas are most often caused by host-specific papillomaviruses.They may also be due to host-specific poxviruses. [1] [4]The transmission of cutaneous fibromas in the white-tailed deer is caused by a virus that is thought to be transmitted through a variety of insect bites or by a deer coming in contact with any contaminated object that scratches or penetrates the skin of the deer or ...
The Centers for Disease Control and Prevention (CDC) have been keeping surveillance on CJD cases, particularly by looking at death certificate information. [37] Chronic wasting disease (CWD) is a prion disease found in North America in deer and elk. The first case was identified as a fatal wasting syndrome in the 1960s.
It is the causative agent of epizootic hemorrhagic disease, an acute, infectious, and often fatal disease of wild ruminants. In North America, the most severely affected ruminant is the white-tailed deer (Odocoileus virginianus), although it may also infect mule deer, black-tailed deer, elk, bighorn sheep, and pronghorn antelope.

Prevalence rates as high as 50% in mule deer near Durango, Colorado; 78% in black tailed deer herd in Mendocino County, California, [13] 90% in mule deer herds at high elevation sites in Arizona and New Mexico, [14] and 100% (14 of 14 animals) in Texas mule deer [15] have been reported. In areas of high abundance in definitive hosts, the fear ...
