Mysterious illness has hit the blue mountains of Washington.
On January 17, a hunter shot a moose cow near the Peaks Peak in the Blue Mountains in the Wall Street Wall. The hunter noticed that the animal hoof deformed. He thus handed the hoof to the Washington Fish and Wildlife Department.
Last week, the Animal Disease Diagnostic Laboratory at the Washington State University confirmed that the mare had an infectious disease, known as a hoof disease, associated with treponemus.
"This is the detection of the farther east, as we documented the hoof disease in Washington," said Kyle Harrison, coordinator of the WDFW, which protects the hoof disease.
. died in the Oregon part of the Blue Mountains, he said. And in February, the disease was confirmed in Idaho near the White Bird. In April, WDFW first confirmed the disease east of cascades.
"This is definitely something we all need to be concerned about," he said. "This is a disease that is very difficult to cope with, and we do not know what the future has for the illness in the blues."
The disease is most commonly found in southwestern Washington, particularly in the mountains of Villap and the mountains of Saint Helens.
A poorly understood illness that resembles a hoof disease that occurs in domestic livestock breeding, originated in Washington DC and has since spread to Oregon and Idaho. 2000s, when observations increased significantly in 2008, Harrison said. However, the disease has not been officially diagnosed until 201
In 2018, the Legislature has allocated 3 million dollars. The full impact of the disease on the population of elk is still unknown.
There was also no origin, – said Margaret Wilde, head of research efforts at the WSU's Goose Goats. Prior to joining WSU in June, Wild worked as the Chief Veterinary Officer for the Service of National Parks. Although there she actively worked on studies of chronic exhaustion of diseases. In fact, it carries out some parallels between CWD and hoofed ears: both of them began as relatively isolated and unknown diseases.
"There are many speculations that go along with this illness," said Wild. The study of the Mount Saint Helens herd began in 2015. Harrison said that the WDFW hopes that the results of the study will be published a year later. But according to preliminary findings, the disease significantly reduced survival rate of the herd, overall body condition and reproduction, said Harrison.
However, the exact impact of diseases on the death of elk is not clear. Harrison noted that the Mount St. Helens had already been fatly challenged and not well-known to be healthy.
For the past fifteen years, Mount St. Helens has declined by 35%. However, at the same time, the state conducted guards who collected more than 1,000 elk of cows to bring the herd in balance with the possibilities of living.
"You know, as many studies, it is difficult to extrapolate," he said.
In 2015, volunteers surveyed the southwest elk rates in Washington. They found at least one lobar elk in 48 percent of all the groups studied. Aerial photography of the same area in the spring of 2017 revealed the lighthouses in 28% of all groups of elks.
And in 2016, researchers from western hunters with elk discovered that 15% collected elk with deformed hoofs. In 2017, Villap Hills collected 10 percent of elk with deformed hoofs and made 17 percent in Mount Saint Helens, said Harrison.
Figures 2018 are not yet available. WDFW now asks all hunters in Washington, – said Harrison
. Although the disease has been documented in Northwest Washington, it has not expanded as it is in the southwest.
Next week, WDFW will launch its annual survey of the Blue Mountains. Harrison hopes the poll will provide more information about blues prevalence.
"We do not feel that there are many other sick elks there," he said. The first step in the construction of a 4-acre body, which will allow them to study the disease from captive animals, said Wild. The key question that researchers are asking about is how prevalence and severity affects the environment. It is believed that the damping climate helps spread bacterial infection.
"I think that as soon as we begin to work in elk, we can tell which environmental factors are important for the onset of the disease," said Wild.
Wild hopes have come to the end, and research has begun by this time of next year. The exact definition of what factors affect the spread and severity of the disease is virtually impossible in the wild, she said.
"It's so hard to identify it in the wild, where you have so many variables that occur at the same time," she said.
At this stage, even if the treatment was found, it would be difficult to deliver
"It's so difficult to manage a disease in a wildlife and a free animal," Harrison said. chronic elk or deformed hoofs.
"I think it's important to know where the disease occurs for a number of reasons," said Dicky. "Once it is created in the area, it becomes much more difficult to manage."
