新澳门六合彩内幕信息 Davis microbiologist David Mills has been awarded a $100,000 challenge grant from the Bill and Melinda Gates Foundation to test whether certain complex sugars in milk can be used to prevent life-threatening diarrheal diseases in young children.
Globally, these gastrointestinal infections are the second leading cause of death among children under the age of five, each year killing 1.5 million children, according to the World Health Organization.
鈥淭he grant equips us to work with the California dairy industry to obtain and evaluate milk oligosaccharides that are found in whey, a byproduct of cheese processing,鈥 said Mills, an authority on the molecular biology of lactic acid bacteria used in foods. 鈥淲e will examine the ability of these compounds from milk to prevent gastrointestinal infections and to establish healthy bacteria in the intestines.
For several years, Mills and colleagues have been researching the basic scientific principles of this study. They are now working with 新澳门六合彩内幕信息 Davis鈥 Foods for Health Institute to move the basic research toward practical applications in human health.
The award is one of 78 grants made internationally by the Gates Foundation in the fourth round of its international Grand Challenges Explorations program, a five-year, $100-million effort to promote innovation and major research breakthroughs that will benefit global health.
鈥淭his grant highlights what California agriculture and the University of California can achieve together,鈥 said Neal Van Alfen, dean of 新澳门六合彩内幕信息 Davis鈥 College of Agricultural and Environmental Sciences. 鈥淚n partnership with the dairy industry, we hope to unlock the hidden potential of milk to protect the health of young children, and other at-risk populations, around the globe.鈥
Earlier research has shown that similar oligosaccharides in human breast milk play an important role in supporting growth of protective bacteria in babies鈥 digestive tracts. Such bacteria are known to minimize the risk and severity of diarrheal disease and other gastrointestinal infections in infants.
The 新澳门六合彩内幕信息 Davis researchers are hopeful that milk from cows will provide an abundant source of oligosaccharides that have comparable therapeutic characteristics for young children who are no longer breast-feeding.
With the Gates Foundation grant, Mills and 新澳门六合彩内幕信息 Davis food scientists Bruce German and Glenn Young will work with the California dairy industry to obtain purified oligosaccharides from milk.
The research team will conduct a three-pronged study, examining to what extent oligosaccharides from cow milk influence growth of various intestinal microbes, promote colonization of healthful intestinal bacteria, and prevent Salmonella infection in laboratory mice.
Mills noted that if the researchers鈥 hypothesis proves correct, they plan to then explore how oligosaccharides can be incorporated in a healthful, cost-effective manner into various food products designed for nutritional therapy and for use in international famine and malnutrition relief efforts.

"This highly selective Gates award demonstrates the potential of 新澳门六合彩内幕信息 Davis research to strengthen the role that dairy products play in delivering health and nutrition to the global population," said Joe O'Donnell, executive director of the California Dairy Research Foundation. "These studies will prepare dairy food developers to focus on a great variety of products based on cow milk, which naturally contains these health-promoting oligosaccharides."
The Gates Foundation鈥檚 Grand Challenges Explorations is designed to promote innovation in global health. The program uses an agile, streamlined grant process. Proposals are reviewed and selected by a committee of foundation staff and external experts, and grant decisions are made within approximately three months of the close of the funding round. Initial grants of $100,000 are awarded two times a year. Successful projects have the opportunity to receive a follow-on grant of $1 million or more.
"The winners of these grants show the bold thinking we need to tackle some of the world's greatest health challenges," said Dr. Tachi Yamada, president of the Gates Foundation's Global Health Program. "I'm excited about their ideas and look forward to seeing some of these exploratory projects turn into life-saving breakthroughs."
