Infographic of the Study (IMAGE) PeerJ Caption We each give off millions of bacteria from our human microbiome to the air around us every day, and that cloud of bacteria can be traced back to an individual. New research focused on the personal microbial cloud -- the airborne microbes we emit into the air -- examined the microbial connection we have with the air around us. The findings demonstrate the extent to which humans possess a unique 'microbial cloud signature.' Credit Image created by Viputheshwar Sitaraman, of Draw Science.
