Raccoons, cats, bees, gorillas, puppies, snakes, chickens, wild birds, ticks鈥haring a planet with animals means we are often either impacting their health, they鈥檙e infecting us or we鈥檙e trading illnesses back and forth. And often the environment is a third-party conspirator.
Our blog, One Health, brings you stories about how 新澳门六合彩内幕信息 Davis researchers and health providers are shifting the dial toward improving the well-being of this triad. One Health is an approach encouraged by medical professionals to ensure the well-being of people, animals and the environment through collaborative problem solving.
We also offer 鈥渉ow-to鈥 advice on helping animals avoid illnesses or coping with potential problems triggered by being close to animals.
I鈥檓 struck by the many threads that weave through the health of animals, humans and the environment. Take a look at these eight stories.
1. How to avoid shared diseases from the ones we love
Over the past several decades, society鈥檚 attitudes have changed on the roles of pets in our lives, and we keep them in close proximity as part of the family. In fact, , which also brings us in closer contact with zoonotic diseases 鈥 particular illnesses that can be shared between humans and animals.
, cautions us on how we can get infected by our pets including:
- Hookworms and roundworms 鈥 intestinal parasites found in puppies and kittens that cause painful, itchy skin infections in humans
- Ringworm 鈥 a fungal infection within the top layer of the skin passed among dogs, cats, horses, other animals and humans
- Lyme disease 鈥 bacteria transmitted through ticks that can become a chronic condition over time, causing nerve and heart inflammation, mental changes and pain
Sykes also offers suggestions about what to do about it if you get infected.
2. Helping birds avoid stress near celebrations like the Fourth of July
Michelle Hawkins, director of the , brings our attention to how fireworks can harm wild birds and offers ideas of how to help our feathered friends.
鈥淧eople can relate to their dogs being affected, but fireworks are also stressful to wildlife and the environment,鈥 she says. In a blog post aimed at people who are using fireworks at home in the country, she recommends that they:
- Wait until dark, when there are fewer birds out in the open air.
- Remove all birdfeeders and baths to avoid drawing birds into areas where fireworks will be happening.
- Clean up the spent fireworks so that potential toxins are not left in the environment.
3. Stem cell treatment for cats offers hope for humans
A , where researchers used stem cells derived from their feline patients, has given Smokey the cat one more of her nine lives. She suffered from chronic gingivostomatitus or FCGS, a painful inflammatory mouth disease.
Smokey鈥檚 treatment has reduced inflammation and promoted new tissue growth. And she鈥檚 back to eating.
Researchers say these in treating a similar oral inflammatory disease 鈥 鈥 which creates ulcers in the mouth, making it difficult to talk and eat. Plans for human clinical trials may begin as early as next year at 新澳门六合彩内幕信息 Davis.
4. Suburbia and humans contribute to raccoon cancer
新澳门六合彩内幕信息 Davis veterinary pathologist says cancer is getting more prevalent among wildlife, based on the increasing presence of raccoon polyomavirus.
Pesavento is a pathologist at the who has spent years studying , a disease which causes serious tumors in raccoons鈥 nasal cavities. These generate intense pressure on the brain, resulting in zombie-like behavior and, ultimately, death.
If you were to have asked Pesavento 10 years ago whether cancer was a major concern in wildlife, her answer would have been a flat 鈥渘o.鈥 But her work with raccoons in recent years has changed her opinion.
She believes that in the past 60-odd years, raccoons have expanded their territory in the U.S. for foraging and picking through abundant human food waste. The change was triggered by the first planned suburb in Levittown, New York, in 1947; similar housing developments swept the nation shortly thereafter. Raccoons, which had previously either lived amid the hazards of the city or scraped by on what they could forage in the forest, suddenly saw their environment transformed.
5. Primate snacks solve a disease-detection problem
Our veterinary researchers in Africa have figured out how to detect viruses in wild mountain gorillas and monkeys without touching them. While chewed plants and sticks might not make a beautiful photo, using them as a health tool really is an elegant solution to a confounding limitation. The team collects discarded sticks and plants and tests them for a variety of viruses back in the lab.
This research is particularly important for mountain gorillas, because only some 880 members of this critically endangered remain in the wild. 新澳门六合彩内幕信息 Davis gorilla veterinarians must go to them in the mountainous , which spans Rwanda, Uganda and the Democratic Republic of Congo, and in the Bwindi Impenetrable Forest in Uganda.
About 60 percent are accustomed to humans as a result of ecotourism in the region. They are at high risk for contacting human viruses and bacteria. In fact, these infectious diseases pose one of the greatest threats to the survival of great apes in the wild.
6. Food-safety tips help you avoid food-borne illnesses when grilling
This post is aimed at the backyard chef, courtesy of . We give you tips to keep your guests healthy, happy and coming back for more.
In a series of five videos, Bruhn demonstrates how to grill a chicken safely. The topics include:
- Don鈥檛 wash your meat
- But do wash your hands again and again
- Keep the meat cold before it hits the grill
- Your thermometers are your best friends
- Know your cooking temperatures
7. Research weighs in on honey bees鈥 and wild bees鈥 futures
新澳门六合彩内幕信息 Davis has devoted itself to the health of bees through much of our history, including developing techniques to artificially inseminate queen bees in the 1940s. Our program, based at , has grown into a comprehensive, state- and federally supported bee facility.
Most recently, 新澳门六合彩内幕信息 Davis has conducted three research projects that could influence the health of bees:
- Figuring out how to weigh a bee: 新澳门六合彩内幕信息 Davis entomologists and an interdisciplinary team of undergraduate engineering students are working on a new tool to weigh bumblebees that far surpasses the conventional lab balance. The entomologists want to understand the health of the hive down to the individual bee, and that requires knowing how much individual bees weigh, as well as fitting them with tiny so that single bees can be tracked entering and leaving the hive.
- Learning that honeybees reduce microbial growth in their food: 新澳门六合彩内幕信息 Davis scientists found that when honey bees shift from nurse bees caring for the brood to foragers searching for nectar and pollen, they turn on a set of genes that protect against microorganisms and break down toxins. These antimicrobials and antitoxins act as preservatives, protecting honey and other stored resources from spoilage. That has implications for hive health and management.
- Analyzing wild bee declines in areas of high-demand crops: A study by 新澳门六合彩内幕信息 Davis and the University of Vermont suggests that wild bee populations likely declined in 23 percent in the U.S. between 2008 and 2013. It鈥檚 a decline associated with converting natural wild bee habitat into intensive agriculture. 新澳门六合彩内幕信息 Davis entomologist Neal Williams helped design the study and led efforts to assess bee habitat quality as part of the He found that areas where crop demand has increased the most showed the greatest decline in wild pollinators.
8. Mission to breed chickens for combating malnutrition
Our poultry experts, led by Huaijun Zhou, director of the , are taking an innovative genomic approach that promises to outmaneuver Newcastle disease, the leading killer of chickens in the developing world. 新澳门六合彩内幕信息 Davis is developing a disease-resistant, heat-tolerant breed of chickens for climate-stressed areas in Africa, where small-scale poultry production has the potential to significantly reduce malnutrition. Threats like Newcastle disease stand as a huge barrier, as they can devastate flocks up to twice a year.
