With approximately 2,000 registered attendees, members of the veterinary and human health communities, scientists, media, policymakers, general public and others showed their concerns about avian flu by tuning into the February 19 UC Health Grand Rounds. The one-hour, online session featured three experts from the UC Davis School of Veterinary Medicine and one from UC Davis Health.
Pasteurization is the only widely recognized method of killing H5N1, the virus that causes bird flu, in milk. However, pasteurization can be expensive and fewer than 50% of large dairy farms pasteurize waste milk.
Waste milk includes colostrum, the first milk after calving; milk from cows treated with antibiotics or other drugs; or any other factor that can make milk unsuitable and unsellable for human consumption. On farms, raw waste milk poses a potential risk of spreading avian flu, which so far has been confirmed in dairy cattle in 16 states.
Bats are widely recognized as the primary hosts of filoviruses, such as Ebola, yet the specific host species of ebolaviruses are not definitively known. In a study led by the University of California, Davis, and the Albert Einstein College of Medicine (Einstein), scientists have developed a new tool to narrow down potential host species of filoviruses and better prioritize wildlife surveillance. The research is part of global efforts to prevent viral spillover between animals and humans.
Last week, the first human death as a result of infection with highly pathogenic avian influenza (HPAI) H5N1, or bird flu was reported. According to the Louisiana state health agency, “The patient contracted H5N1 after exposure to a combination of a non-commercial backyard flock and wild birds.”
Whale researchers dropped a mic into the seas off southeast Alaska and recorded a humpback making a “whup”-like noise, translated roughly as a humpback hello. The next day, they lowered a speaker into the water and played the recorded “whup” back as a pod of whales passed by. One whale, a middle-aged female named Twain, responded in kind. For 20 minutes, Twain and the scientists “whupped” back and forth, 36 times in a row. Researchers even varied the timing of their calls and Twain matched their tempo.
When Sarah Lindley found a lump near her dog Bucky’s tooth, she didn’t think it was a problem. The lively husky mix, which she and her partner, Tom Yuzvinsky, consider part of the family, didn’t appear to be in pain. Still, she scheduled an appointment with her local veterinarian on the Central Coast.
“At first we thought something was stuck in his gums and he might lose a tooth,” Lindley said. “Then the biopsy came back as cancerous.”
Researchers at the UC Davis School of Veterinary Medicine marked a milestone in equine assisted reproductive technologies with the first successful use of frozen-thawed sperm for in vitro fertilization (IVF) production of equine embryos. These promising results, just published in Theriogenology, have the potential for broader clinical applications, as well as valuable opportunities to study fertilization and embryo development.
A recent clinical trial conducted by the UC Davis School of Veterinary Medicine has shown that famciclovir, an antiviral used to treat feline herpes, hastens recovery in kittens with infectious upper respiratory disease (IURD). The results of the research, published today in the Journal of Feline Medicine and Surgery, also indicated that the drug may also reduce corneal disease in some of these kittens.
