By Simon Hradecky, created August 16, 2018 06:55:21More than 100 dogs from the United States, Australia and Japan are believed to have been infected with the canine immuno-suppressor virus, which has killed about two million dogs in the past decade.
Researchers from the National Institute of Allergy and Infectious Diseases in Bethesda, Maryland, who analysed more than 3,000 dogs from a database of more than 30,000, said there were several cases of canine immunoglobulin E, or IgE, antibodies in the dogs’ blood.
They did not say whether the dogs were infected by the virus.
The results, published in the journal Science, came as a surprise to dog breeders, who have been waiting for the virus to be detected in the wild and have raised the prospect of reintroducing the species into the United Kingdom and the United Nations.
Dog owners are increasingly concerned about the virus, after being told for years that it was not a threat.
The US Centers for Disease Control and Prevention said last month that the number of confirmed cases of I.V.-HIV in dogs was down more than 40% in recent years, but the number who contracted the virus was still at the highest level recorded.
Dr Jody Williams, an infectious disease specialist at Emory University in Atlanta, Georgia, who studies canine infection, said the news of the new study was a “game-changer” and said the results were a “tremendous relief”.
“The number of cases has been declining steadily over the past few years and we really don’t have any reason to believe this will be a problem for our breed,” she said.
“But we need to start making some changes because it’s going to be very difficult to reintroduce the dogs to the wild without killing them.”
The virus is found in about two-thirds of all dogs, although it is less common in people, because they have lower immune systems and are more likely to live in areas where they are vaccinated.
The CDC reported that in the US alone there are more than 500,000 confirmed cases and 531,000 deaths in dogs.
It is estimated that up to one million dogs worldwide are infected, with up to 1.6 million people believed to be carriers of the virus worldwide.
The virus, like other canine infections, has killed many of its victims by spreading through the bloodstream.
In some cases, it has also caused serious illness in dogs, leading some to become euthanised or die from their illness.
It was first detected in humans in a dog from New York state in March 2018.
Dr Williams said the new data suggested that the disease could be spreading more quickly than previously thought.
It’s very worrying. “
I think we’re going to start to see more and more dogs die,” she added.
“It’s very worrying.
What we’ve seen in the UK and in Australia is that they’ve been able to vaccinate these dogs, but in some cases there’s been resistance to vaccinating them and then they’ve killed their puppies.”
Dr Williams, who works with the UK Dog Vaccine Initiative, said she had seen some dogs who had not been vaccinated in the lab with resistance to the vaccine.
“If that means that they have the [IgE] antibodies and that the vaccine is ineffective, that’s a huge concern because it means that these dogs are not going to get the vaccine,” she explained.
“I would really be worried about that, because if they don’t get the vaccines, they are going to die.”
The United Nations announced last week that it would reintroduce some dogs from South Africa and the US to the UK after the country became the first country in the world to pass legislation allowing dogs to be vaccinated.
Dr Williams and other dog breed researchers said that if the new results were confirmed, the vaccine might still be useful.
“We’re hopeful that the vaccination could be effective for some dogs, as there are a number that haven’t had a vaccine,” Dr Williams said.
“I really do believe that it will be helpful for some breeds, for people who can’t get vaccinated.”
Dr Jamin Cairns, of the University of York, said: “It is still too early to tell, but it is likely that there is a good proportion of dogs who haven’t received the vaccine and the risk of getting the disease is increased.”
The UK Dog Association said it was “deeply concerned” by the news.
A spokesman said: “We have been working hard to vaccine as many dogs as possible to ensure we have a safe and effective vaccine, and are committed to working with all our stakeholders, including the veterinary community, to develop a vaccine that works for the dogs we currently have
