Posh ‘natural’ pet food recalled as cats and their owners develop bovine tuberculosis.Fifty pedigree animals on a pricy gourmet diet have been taken ill and at least one has died, with two people also infected..A luxury cat food designed for pedigree pets has triggered an outbreak of a deadly strain of tuberculosis that has infected 50 cats and at least two of their owners. The “natural cat” wild venison cat food has been subjected to a nationwide recall by Natural Instinct, the company which sold it to thousands of cat owners as a healthier alternative to mass-produced pet food. It follows research by veterinary scientists at Edinburgh University who investigated why 50 cats in 30 homes around Britain had developed bovine tuberculosis (bTB). Almost all the cats were expensive pedigrees whose owners kept them indoors, meaning they had no contact with livestock or wild animals which can carry such infections. The one thing all the cats had in common was that they were fed Natural Instinct’s raw wild venison cat food which costs about £4.50 for two daily portions, compared with under 20p for a typical dried cat food. Bovine TB is related to human TB and is now so common in UK cattle that strains are infecting wildlife such as badgers, foxes and deer. Danielle Gunn-Moore, professor of feline medicine at Edinburgh University, who co-authored the research, said: “Raw meat diets could be good for cats, in theory, but there is a clear risk of infection so checks are vital. It’s not just bTB — there’s also a risk of toxoplasmosis, salmonella and other pathogens.”She and her colleagues gathered reports of bovine TB in cats in 30 households around the UK. The team had to test 90 felines and refer 100 people for tests. Two people have been found to be infected but more could emerge.

Bovine birthing simulator used to educate veterinary students on display at Agribition.Meet Agnes — she's a full-size cow, with a working udder, a uterus and a full-size calf but she's not quite a real cow. Instead, the bovine specimen is used to educate veterinary students and cattle producers about the cattle birthing process.#bovine "We can actually use her, mainly to educate ... in the birthing process, and how to deal with any sort of malpresentations at the birthing time," said Chris Clark, associate dean of the college of veterinary medicine at the University of Saskatchewan. #bovine

Researchers have found antibodies to the newly discovered influenza D virus in pigs, cattle, horses, goats and sheep, but not poultry. A researcher has proven that the guinea pig can be used as an animal model and is developing a way to study the virus in living cells—trachea and lung epithelial cells from swine and cattle. To identify exposure to the virus, South Dakota State University doctoral student Chithra Sreenivasan tests blood samples for influenza D antibodies. Working with the Minnesota Poultry Testing Lab, she found no evidence of the new influenza strain in poultry; however, she did find antibodies to the virus in sheep and goats from the Midwest through blood samples archived at Washington State University. The virus has not been shown to be pathogenic in humans, the goal is to determine whether the virus can cause problems in humans.If the virus can undergo reassortment in combination with a closely related human influenza virus, it may be able to form a new strain that could pose more of a threat to humans. Using the bovine Influenza D strain, Sreenivasan proved that the guinea pig could be used as an animal model to study the virus. Though guinea pigs showed no symptoms, she successfully isolated antigens in tracheal and lung tissues. In addition, her research showed the virus is spread only through direct contact. Those results were published in the Journal of Virology, with Sreenivasan as the first author of the article. Influenza D has about 50 percent similarity to human influenza C. Human C affects mostly children, the most common symptom is a runny nose. It's not a serious disease as we all have some antibodies because we were infected as children. source; science daily.
