A mysterious brain disease is causing young people California black bear It becomes more “dog-like” and less afraid of humans.
Due to neuropathy, wild animals behave excessively friendly and become completely comfortable around people.
Last year, four Cubs showed symptoms, according to the California Department of Fish and Wildlife (CDFW).
Their actions, including the subtle tilt of their heads, confused veterinarians and biologists.
After approaching the people of the North Star Ski Resort, a video of a young black bear became prominent on social media.
The bear stepped into the snowboarder’s board while filming the encounter and posting it on Instagram.
The bear, now named Benji at the age of three, has been moved to a facility run by the San Diego Humane Society, which is being treated by a veterinarian.
Another similarly affected young bear appeared last month at a utility plant in Pollock Pines, El Dorado County.
The· The bear showed little fear And I ignored the screams and applause aimed at getting rid of it.
After that, I moved to the backyard of the house and the locals started eating apples and strawberries.
“At some point, the bear jumped into the trunk of a housekeeper’s open car and urged him to approach it and try to keep a pet,” said a CDFW spokesman.
Wildlife officials who visited the bear said it behaved “dog-like”.
It sat on the backyard patio, picked up an apple and ate it in front of them. Locals said they became obsessed with it.
A CDFW spokesman said, “Bear physically and mentally did not look right at all, walked strangely, was dull and did not react like a normal bear.”
It was taken to a laboratory where veterinarians could observe the animals.
They found it to have intermittent head tremors and tilted heads. And it indicates a neurological abnormality.
Bears were also only a quarter of the average black bear of that age.
Finally, he was euthanized and a post-mortem examination was performed.
Scientists have discovered encephalitis, an inflammation of the brain usually caused by a virus. The fourth recent incident in the area.
“At this point, we don’t know the cause of encephalitis, so we don’t know if these bears could pose a health risk to other animals,” said Dr. Brandon Munch, a CDFW veterinarian. I will.
A young black bear in this condition was previously identified in the neighboring state of Nevada.
The Nevada Wildlife Service said there were increasing encounters between humans and bears showing neurological abnormalities in the forested Tahoe basin area.
This month, veterinarians and biologists from two state wildlife agencies met to assess the issue.
They discovered five new viruses while investigating the affected bears, but it’s unclear if any of them was the cause.
California black Bear population has tripled Over the last 40 years, it is now up to 40,000.
Bears have become less restrained around people, and it has become more common to wander into the garden or home in search of food.
The close proximity to humans also causes fear of the virus’s jumping species.
However, Jamie Sherman, a veterinarian at the University of California, told The Sacramento Bee that “the viruses detected in these bears were not particularly known to affect humans.” ..
