Sugar on bacteria surface serves as base for a web of resistance
COLUMBUS, Ohio 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.
Scientists have determined that the bacterial cell-surfa...
Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward
