WASHINGTON – It sounds like a plot from The Walking Dead.
Deer concludes a mysterious illness. Symptoms include vacant eyes, thick saliva, bulging ribs, lowered heads – but do not have behavior beyond the normal range of deer activity. They can live for two years. Then, one day, they are becoming overly aggressive – thus, a "zombie" caricature – before death.
A major concern is that people ate mice of infected deer, raising fears that the plague could cross the species.
] The real issue of what is called "zombie deer disease" is "chronic abortion." It was first spotted in 1
Chronic illness, or HZD, passes from animals to animals through prions, improperly composed proteins that cause incorrect folding of proteins around them. Different prion diseases, as a rule, damage only certain species, but can develop to overcome these constraints.
The following states reported this illness: Arkansas, Colorado, Illinois, Iowa, Kansas, Maryland, Michigan, Minnesota, Mississippi, Missouri, Montana. , Nebraska, New Mexico, New York, North Dakota, Pennsylvania, South Dakota, Tennessee, Texas, Utah, Virginia, West Virginia, Wisconsin and Wyoming.  In some herds, as half the animals bear prions.
But direct contact is not the only way to transfer prions. Sick animals and corpses can spread prions through plants and soil, which can be coated with deformed proteins for many years, perhaps even decades.
Although no human illness has been reported through illness, and scientists have no convincing evidence. that infected people once hurt people, wildlife officials in Colorado and Pennsylvania insist on hunting rules to be safe.
And there are more reasons to worry.
The Canadian study added that the consumption of infected deer can spread the disease to other species – including humans. An outstanding prion researcher, Stephanie Czub of the Canadian Food Inspection Agency, found three of the ape-fed African infected mice tested positive for chronic lung disease.
In the study, 18 macaque macaques were subjected to CED in a variety of ways – the extraction of material into the brain, through contact with the skin and by feeding them with infected mice. It was reported that this was the first case when the disease spread to primates by eating deer.
"It is believed that chronic exhaustion of the disease does not pose a health threat to humans," said Czub. "But with new data, it seems we need to redefine this idea to a certain extent."
The study was funded by the Research Institute of the Alberta Prion at the University of Calgary and began in 2009. According to the Office for Food and Drug Administration, 231 people died from eating beef infected with "the disease of crazy cows."
Mark Zabel, Associate Director of the Prion Research Center at the State University of Colorado, said prions are involved in "zombie disease." About which scientists know only 50 years are likely to still evolve. Zabele believes that the only way to get rid of pneumoniae CWD is to install controlled fires.
According to Michael Miller, senior veterinarian for wildlife parks and wildlife in Colorado, the infection of deer mules increased more than threefold by the end of 2017, while CWD continues
"What we have seen in the last few decades is a slow spread in populations of wild deer, "said Peter Larsen, associate professor at the Department of Veterinary Science at the University of Minnesota. It also spreads among captive deers, moose and deer, which are transported across the country and abroad to hunting ranches, zoos and farms on Christmas. Thus, the disease ended in South Korea, explained Larsen.
On March 13, 2005, a fire company in the Onyide County, New York state, fed a wild deer that was positive for a chronic disease of 200 to 250 people. The company did not know that it was in deer sick. Laboratory tests for one of the deer serviced back later – positive for HZD.
Over time, the Department of Public Health of the District of Oregon monitored the health of the group through a monitoring project. About 80 people who ate the game, agreed to take part. Together with the State University of New York-Binghamton, health experts checked the group for six years to find out if they have any unusual symptoms.
In a study published in the peer-reviewed Public Health Journal, the researchers found that the group did not have "significant changes in health," although they reported that they ate less venison after the entire test. Otherwise, observable conditions, including loss of vision, heart disease, type 2 diabetes, weight changes, hypertension and arthritis, were enrolled to old age.
