A University of Calgary researcher will lead a North American study examining a new way to treat E. coli infections that can cause kidney failure in children. The university says the U.S.-based National Institutes of Health is providing more than $11 million for the investigation, meant to stop disease from progressing from bloody diarrhea to kidney shutdown and neurologic complications. The University of Calgary says Alberta has one of the highest rates of STEC infection in the world given its abundance of cattle, sloped terrain, food crops and use of well water.
