Narrator: This is Science Today. One of the major causes of death in young children in developing parts of the world is diarrhea. So, a team of researchers at the University of California, Davis, modified goat's milk to produce an antimicrobial protein called lysozyme in the hopes of speeding up recovery and saving lives. Animal science expert James Murray led the study.
Murray: Lysozyme is an enzyme which actually digests bacteria, so it destroys certain kinds of bacteria by digesting the outer cell wall that holds them together.
Narrator: Murray explains that lysozyme is found in human breast milk.
Murray: And so we've now tried to put that protein into milk of ruminants so that it would be available then to young children in the world who are suffering things like debilitating diarrhea.
Narrator: The team has conducted safety tests with the milk by feeding it to young pigs and kid goats, but Murray says the next step is conducting human clinical trials with partner universities in Brazil, where childhood diarrhea is a problem. For Science Today, I'm Larissa Branin.
