This construction formulated from 14 studies published in the journal Nature and the Public Library of Science.
The study lasted 5 years with 240 participants at St healthy living. Louis and Houston (USA). The researchers took samples from 15 locations on the body position of men and 18 women's body. The research location is the mouth, skin, nose and intestines.
The scientists said more than 10,000 microorganisms in the human body. With a 90 kg, about 1-3 kg of bacteria, the bacteria live.

Bruce Birren, director of the Center for Gene Order infections, and also director of the Program Analysis and Sorting of genes at MIT Harvard University (USA) said: "Eight million microbial genes from 10,000 this microorganism playing a key role in the development and health of us"
It is interesting that bacteria on this human body are very different from other human bodies, especially on the skin. In addition, microorganisms are also different in each person; this suggests that people have the "signature" of bacteria in particular.
However, these microorganisms may be different but their function for the human body are the same.
