SAN DIEGO, May 31 (UPI) -- A study of offices in three U.S. cities found men's offices have significantly more bacteria than women's, researchers said.
Dr. Scott Kelley of University of California, San Diego, identified more than 500 bacterial genera in offices in New York, San Francisco and Tucson and found the most abundant tended to come from human skin or the nasal, oral, or intestinal cavities.
