Mapping spread of diarrhea bacteria a major step toward new vaccine

11 noviembre 2014

Enterotoxigenic Escherichia coli (ETEC) bacteria are responsible each year for around 400 million cases of diarrhea and 400,000 deaths in the world’s low- and middle-income countries. Children under the age of five are most affected. ETEC bacteria also cause diarrhea in nearly one in two travelers to these areas. In a major breakthrough, researchers used comprehensive DNA analyses to reveal the ETEC bacteria’s genetic composition – an analysis that also makes it possible to map how the bacteria spread.
