Cystic Fibrosis: Sugar On Bacteria Surface Serves As Base For Web Of Resistance

The bacteria responsible for chronic infections in cystic fibrosis patients use one of the sugars on the germs' surface to start building a structure that helps the microbes resist efforts to kill them, new research shows.
