Ontario 07/03/12 laurentian.ca: News Release – A team of Laurentian University biology researchers has found significant evidence of the spread of the zoonotic bacterium Coxiella burnetii in wildlife in Algonquin Park. A zoonotic disease is one that can be transmitted to humans from animals. The C. burnetii bacterium causes Query fever or “Q-fever” in humans. It was detected in 6 out of 7 species of wild rodents tested within the boundaries of Algonquin Park, including red squirrels, flying squirrels and deer mice. It was also found in flying squirrels in the Peterborough area, indicating that the bacteria may be widespread among these animal populations in Ontario.
Researchers say Coxiella burnetii is generally found on farms with small ruminants, but little is known about transmission of the bacteria from the natural environment. The researchers, led by Canada Research Chair Dr. Albrecht Schulte-Hostedde of Laurentian University, say their findings suggest that some visitors to Algonquin Park could be at risk of infection. “The bacteria that cause Query fever can make humans quite sick, so this is an important finding,” said Dr. Schulte-Hostedde. “We’re still trying to learn how Coxiella burnetii is maintained and spread in the natural environment. We don’t know yet whether wild species are picking it up from domesticated animals, and we don’t know how it changes as it moves between species. As we learn more about it, we’ll have a better understanding of the potential risk to human health.”
Dr. Schulte-Hostedde is Canada Research Chair in Applied Evolutionary Ecology at Laurentian University. Among other areas of study, he has studied squirrel populations in Algonquin Park for more than 10 years. “We were certainly surprised to find such a high prevalence of Coxiella burnetii in Algonquin, given the amount of human traffic in the area,” said Dr. Schulte-Hostedde. “There are hundreds of thousands of visitors to this park in a year, so it’s good news that so far there are no confirmed reports of Q-fever traced back to the Park.” People diagnosed with Query fever are usually infected through contact with sheep, goats or cattle. The resulting illness may cause fever, flu-like symptoms, and occasionally swelling of the lining of the heart and heart failure. The last significant outbreak was in the Netherlands in 2007 and led to the infection of more than 2,000 people and the culling of thousands of goats. The results of the Laurentian research are being published in the latest issue of the scientific journal Zoonoses and Public Health.
Alberta 07/04/12 cbc.ca: Farmers near Mayerthorpe are on high alert after wolves attacked animals in two separate incidents over the past two weeks. Three cows were slaughtered in one case; a mare and donkey were attacked in the other. The latter incident occurred earlier this month on Merle Arthur’s horse and mule farm near Mayerthorpe. The attack shocked him because donkeys usually keep wolves at bay. “If you or I were to run up and grab him by the hind leg, we wouldn’t wake up for about a week — if we woke up,” Arthur said. “So he would have put up an awful fight. It would have been more than one wolf. It would have been a pack of wolves that did this.” Arthur had to shoot the donkey because it was so badly injured.
Cattle farmers can get compensation, but Arthur won’t be able to claim anything for his donkey. “They’re not considered a specific meat-producing animal,” said local wildlife officer Greg Gilbertson. “So the program doesn’t cover those types of animals.” Arthur says the loss of his donkey will be a financial set-back as it was the only male he owned for breeding. “This is my living,” he said. “This is what I do and them wolves took a good part of it away.”
