Researchers at Harvard Medical School have identified a bacterium as the possible cause of itchy skin diseases, such as eczema or dermatitis, and—most importantly—potential effective treatments to help stave off the pesky irritation.

In a study published in the Nov. 22 issue of the journal Cell, researchers reported that exposure to the bacteria Staphylococcus aureus (S. aureus) triggered the nervous system in mice to send signals from the skin to the brain. Researchers also conducted the experiment in laboratories using human cells.
“We’ve identified an entirely novel mechanism behind itch—the bacterium Staph aureus, which is found on almost every patient with the chronic condition atopic dermatitis. We show that itch can be caused by the microbe itself,” said senior author Isaac Chiu, associate professor of immunobiology at Harvard, in a statement.
