Simon Park, with the help of his Practical and Biomedical Bacteriology class, demonstrates just how disgusting your smartphone screen really is. Olivia Solon squirms:

According to Park, most of the bacteria were harmless ones normally found on the skin, such as the Micrococcus species. However, disease carrying bacteria such as Staphylococcus aureus were also found. Park is not surprised by this as around 20 percent of people persistently carry the bacterium, while 60 percent of us are intermittent carriers.

“The ecological niche on the body for Staphylococcus aureus is the nostrils, so a furtive pick of the nose, and quick text after, and you end up with this pathogen on your smartphone,” Park explained to Wired.co.uk.
