Last year, microbiologist Jack Gilbert showed, along with other scientists, that every family has a aura characteristic that unlike other bacteria
Since then became a key. Question: could the communities of bacteria found in the personal property of a person reveal their latest moves?

A recent flurry of research is providing new data about the enormous variety of bacterial life that lives on our body and inside him and is known as the human microbiome.
These studies were released that we humans We spent about 124 million bacteria with a simple handshake (fives transmits half) and about 80 million in a tongue kiss.

These communities of billions of bacteria are also associated with diabetes, cancer and other diseases. Everyone seems to have an almost unique bacterial firm and its objects, too.
In a study published today, Gilbert shows and other colleagues that these bacteria in our personal items serve to rebuild what have been our last steps, some results are already trying to apply to the courts to identify suspects without human DNA, single bacterial.
“We demonstrated that go from your living room to a Friend results a major change in the structure of the microbial community of your personal items that we can detect, “Simon said in a statement Lax, a researcher at Argonne National Laboratory (USA) and coauthor of the study, published in Microbiome .

Experts took samples of mobile phones, shoes and the ground underfoot two people for two days. Bacterial DNA analyzes show that microbial communities in the shoes change quickly depending on the soil and its characteristic composition can be used to reconstruct the last movements of a person.
