What is discovered by scientists at Brown University?

Scientists at Brown University in the Northeastern United States [27] discover that bacteria from yogurt can be made into a substance that helps fight HIV. Led by Professor Bharat Ramratnam, they modify the bacteria to cream cyanovirin—[28] a protein that protects the body from infection by microorganisms such as bacteria, viruses, and fungi. The hope is to use the bio-engineered yogurt bacteria as the active ingredient in a foam, cream or suppository that can be applied before sex to prevent HIV transmission.
