A University of Wisconsin-Madison biochemistry professor has developed a simple bacterial test that could be used to save infants? lives in developing countries, after the Bill and Melinda Gates Foundation granted him $100,000 for the project, according to a UW-Madison news release. UW-Madison biochemistry professor Douglas Weibel?s laboratory created a cartridge test to determine if the type of bacteria in a newborn?s stomach must be treated to prevent a common, often deadly, bacterial infection that kills intestinal tissue.
