Experts decode germs' DNA to fight food poisoning

This photo taken Nov. 25, 2013 shows microbiologist Heather Carleton pulling up results of Listeria bacteria DNA while demonstrating a whole-genome sequencing machine called a MiSeq in a foodborne disease outbreak lab at the federal Centers for Disease Control and Prevention in Atlanta. The nation's disease detectives are beginning a program to try to outsmart outbreaks by routinely decoding the DNA of deadly bacteria and viruses. The initial target: Listeria, a kind of bacteria that's the third-leading cause of death from food poisoning, and one that's especially dangerous to pregnant women. Already, the technology has helped to solve a small listeria outbreak that killed one person in California and sickened seven others in Maryland.(AP Photo/David Goldman)
