Microbiologists found in human skin 182 microbes living, they are part of a permanent "resident there," and the other only occasionally "patronage".
New York University School of Medicine of microbiologists Martin · blaehser, said a long time people know, in human skin perched large numbers of bacteria, but blaehser and his colleagues in the accurate statistics, use a highly complex, DNA-based molecular techniques.
Researchers from six health human forearm taken a swab specimens for research in human skin on bacterial communities. They found out about 182 bacteria, than previously expected more, which is about 8% previously not known, but bacteria species because of sex.
Blaehser said: "micro-organisms may have on animals have billions of years of life. The human body by bacterial species is not random. They are human beings with evolution. ”
He added: "we believe that many micro-organisms on our skin has a protective effect. So I don't quite agree with frequent cleaning, because this was actually our protection layer to wash away. ”
Some bacteria are unicellular microorganisms, people believe that they are first appeared on Earth. Although some bacteria can cause disease, but often also inhabit the bacteria in the human body, such as the digestive tract, to do some useful things. If you do not have these probiotics, humanity cannot survive.
