An anonymous reader writes: According to a new study, we are all surrounded by a personal "germ cloud" as unique as a fingerprint. Lead author of the study Dr James Meadow says: "We expected that we would be able to detect the human microbiome in the air around a person, but we were surprised to find that we could identify most of the occupants just by sampling their microbial cloud. Our results confirm that an occupied space is microbially distinct from an unoccupied one, and demonstrate for the first time that individuals release their own personalized microbial cloud." The findings were published today in the journal PeerJ.
