The weird relationship between bacteria and their human hosts

Perhaps gonorrhea should be worried about what it's catching from us. A team of scientists say they've found evidence that the sexually transmitted bacterium has, at some point in its long history, picked up fragments of human DNA. If this research is verified, it will mark the first known example of human DNA finding its way into a bacterial genome. So far, nobody knows whether the human DNA gives the gonorrhea some advantage, whether it's a detriment, or whether it's just a weird, neutral fluke.
