Genetically Modified Goats Helping to Save Lives
More than a dozen goats at UC Davis have been genetically engineered to include a single human gene that gives the goats' milk extreme bacterial fighting properties. The end goal is to use these goats to help end diarrhea, the number one killer of children worldwide, from unclean drinking water and other sources.
A study Murray and his team published in 2008 in the Journal of Nutrition found that feeding pigs the lysozyme-enhanced milk did their stomachs good. Compared to a control group, the genetically enhanced stuff significantly cut coliform bacteria in the pigs’ small intestines. And a more recent study observed that the milk both tamped down inflammation in the gut while also beefing up the cells that serve as the intestine’s first line of defenses against bacteria.
