New coronavirus emerges from bats in China, devastates young swine.

New coronavirus emerges from bats in China, devastates young swine. A newly identified coronavirus that killed nearly 25,000 piglets in 2016-17 in China emerged from horseshoe bats near the origin of the severe acute respiratory syndrome coronavirus (SARS-CoV), which emerged in 2002 in the same bat species. The new virus, called swine acute diarrhea syndrome coronavirus (SADS-CoV), doesn't appear to infect people, unlike SARS-CoV which infected more than 8,000 people and killed 774. No SARS-CoV cases have been identified since 2004. The study investigators identified SADS-CoV on four pig farms in China's Guangdong Province.

More communication needed regarding disposal of pet pharmaceuticals.

More communication needed regarding disposal of pet pharmaceuticals.New research found that more than 60 percent of veterinary care professionals do not counsel their clients when it comes to the environmental stewardship aspect of medicine disposal. New research from Oregon State University found that more than 60 percent of veterinary care professionals do not counsel their clients when it comes to the environmental stewardship aspect of medicine disposal -- findings that are troublesome but also represent an opportunity to dramatically reduce watershed contaminants. "People are just starting to understand the impact that discarded pharmaceuticals and personal care products have on the environment," said the study's corresponding author, Jennifer Lam, who worked on the research while a graduate student in marine resource management at Oregon State University.

Dogs could be more similar to humans than we thought.

Dogs could be more similar to humans than we thought.Dog and human gut microbiomes have more similar genes and responses to diet than we previously thought, according to a new study. Dog and human gut microbiomes have more similar genes and responses to diet than we previously thought, according to a study published in the open access journal, Microbiome. Dr Luis Pedro Coelho and colleagues from the European Molecular Biology Laboratory, in collaboration with Nestlé Research, evaluated the gut microbiome of two dog breeds and found that the gene content of the dogs microbiome showed many similarities to the human gut microbiome, and was more similar to humans than the microbiome of pigs or mice.

Dogs prefer to eat fat, and cats surprisingly tend toward carbs.

Dogs prefer to eat fat, and cats surprisingly tend toward carbs.Dogs gravitate toward high-fat food, but cats pounce on carbohydrates with even greater enthusiasm, according to research into the dietary habits of America's two most popular pets. The study sheds new light on optimal nutrition for the animals and refutes a common notion that cats want and need a protein-heavy regimen.Findings were published this month in the Journal of Experimental Biology. "The numbers were much different than what traditional thinking would have expected," said the study's corresponding author, Jean Hall, a professor in the Carlson College of Veterinary Medicine at Oregon State University. "Some experts have thought cats need diets that are 40 or 50 percent protein. Our findings are quite different than the numbers used in marketing and are going to really challenge the pet food industry." Dietary proteins contribute to a number of important physiological functions such as blood clotting, production of hormones and enzymes, vision and cell repair. Protein also has the most power to make the eater feel satiated; carbohydrates are No. 2 in that regard, followed by fat.

Human encouragement might influence how dogs solve problems.

Human encouragement might influence how dogs solve problems.A new study sheds light on how people influence animal behavior. Researchers evaluated the behavior of search and rescue dogs and pet dogs when presented with the same problem-solving task. Both sets of dogs persisted at the task for about the same proportion of time, but the search and rescue dogs were more successful at solving the task when encouraged by their owners. Human encouragement might influence how dogs solve problems, according to a new Oregon State University study. The study, published in the journal Applied Animal Behaviour Science, sheds light on how people influence animal behavior, said study lead author Lauren Brubaker, a doctoral student in OSU's Human-Animal Interaction Lab. Brubaker evaluated the behavior of search and rescue dogs and pet dogs when presented with the same problem-solving task. Both sets of dogs persisted at the task for about the same proportion of time, but the search and rescue dogs were more successful at solving the task when encouraged by their owners.

French bulldogs at risk of various health problems.

French bulldogs at risk of various health problems.French Bulldogs, predicted soon to become the most popular dog breed in the UK, are vulnerable to a number of health conditions, according to a new study published in the open access journal Canine Genetics and Epidemiology. Researchers at The Royal Veterinary College (RVC), UK found that the most common issues in French Bulldogs over a one year period were ear infections, diarrhea and conjunctivitis (inflammation of the eye surface). Dr. Dan O'Neill, RVC Senior Lecturer and the main author, said: "French Bulldogs are a relatively new arrival to the list of common UK breeds so there is very little current research on them in the UK. Our study -- the first on this breed in the UK -- is based on anonymised records gathered from hundreds of UK vet clinics. It provides owners with information on the issues that they could expect and should look out for in French Bulldogs. It may also help potential new owners to decide if a French Bulldog really is for them." Dr. O'Neill adds: "One of the interesting finding from our research is that male French Bulldogs appear to be less healthy than females. Males were more likely to get 8 of the 26 most common health problems while there were no issues that females were more likely to get than males."

How Nagana or Animal Trypanosomiasis is carried by tsetse flies .

How Nagana or Animal Trypanosomiasis is carried by tsetse flies . Researchers at the University of Bristol have revealed new details on how the animal disease Nagana is spread by tsetse flies in Africa. When animals are bitten by bloodsucking tsetse flies, they don't just get a painful bite, as the flies may be carrying a cargo of deadly microbes, trypanosomes. These microbes are squirted into the skin of the animal as the fly feeds and invade the bloodstream, causing the severe and sometimes fatal disease Nagana or African Animal Trypanosomiasis. Most livestock are susceptible to this disease including cattle, sheep, goats, pigs and horses. Tsetse flies pick up the microbes when they take blood from an infected animal. The blood is digested inside the gut of the fly, but the trypanosomes need to find their way back to the mouthparts so that they can be passed on to the next animal the fly bites.
