Your smartphone is filthy, and I don’t just mean what’s in your browser’s search history folder. A group of scientists have discovered that our cell phones carry our their owner’s individual devil’s brew of bacteria: A house blend of staph, strep, and other biological goodies.

To test our biological connection with phones, University of Oregon researchers sequenced microbes from the dominant-hand index fingers and thumbs of 17 subjects and from the touchscreens of their smartphones, during a recent Robert Wood Johnson Foundation workshop in Princeton, New Jersey. The study found smartphones closely resembled the microbiome sampled from their owner’s finger, with 82 percent of the most common bacteria on participants’ fingers also found on their phones.
Interestingly, women were found to be more closely connected, microbiologically speaking, to their phones than were men. Although men and women were both statistically similar to their own phones, the relationship was stronger for women than for men.
