（单词翻译）

 But can a person’s unique signature of hand bacteria be used to identify them, much like DNA1? A handful of experiments say yes.

For example, researchers at the University of Colorado, Boulder2 took bacteria samples from computer keyboards.
They compared them to hand bacteria samples taken from the computers’ users, and to samples taken from people who’d never used the keyboards. The keyboard samples matched up much better with bacteria from the computer owners’ than they did with bacteria from strangers.
More studies need to be done to see if hand bacteria really are useful as a forensic3 tool. But as a complement4 to DNA and fingerprints5, it could prove a reliable way to put away the bad guys.
