Men's offices harbor significantly more bacteria than women's, according to a new study published in the online journal PLoS ONE.
The types of bacteria are the same, and come mostly from the skin, nose, mouth and digestive tract. Several types are also commonly found in feces.
Researchers from the San Diego State University and the University of Arizona took 450 samples from different office surfaces in New York City, San Francisco and Tucson, Ariz.
Chairs and phones had the highest amount of bacteria, while desktops, keyboards and computer mice had fewer bacteria.
One of the main reasons the researchers did the study was to learn more about what microorganisms inhabit workplaces.
