Human body skin is a bacterium " the zoo

The skin is the organ with the largest human body, the bacterium that the scientist gets on to living in human body skin first has detailed investigation, the result discovers human body skin is a bacterium actually " the zoo " , there are 250 kinds of bacteria about here, wh some of which is " often live dweller " , additionally a few are belonged to " hobo " .
The scientist thinks, this discovers microbial to human body research has important sense.
Scientist discovery, sheet is there are about 182 kinds of bacteria on the antebrachium in everybody, divide in all it is 91 kinds, the bacterium that has 8% among them is done not have by the scientist official record.
The United States that this studies to achievement is published in 5 days " journal of national academy of sciences " go up, this research project by American new York about professor of a place of strategic importance of · lay mines chairs the man of microbiology home horse of the college of medicine.
Have 250 kinds of bacteria at least
Lay mines a place of strategic importance is being accepted when interviewing, say, "We reckon human body surface is living at least 250 kinds of bacteria. "We reckon human body surface is living at least 250 kinds of bacteria..
Lay mines a place of strategic importance emphasizes saying, "A good zoo also has 100 to plant nevertheless or 200 kinds of animals, the bacterial sort that we discover in surface of human body skin at present has so much, the antebrachium that is human body merely is a pretty good bacterium ' the zoo ' . The antebrachium that is human body merely is a pretty good bacterium ' the zoo ' ..
According to estimation, microbial amount and scale of amount of human body cell are human body 10: 1. People is in all the time the whole microbial modes of life and relation to their environment that tries to study human body, this second research can say the one share that is this one effort.
People is the bacterial cent of surface of human body skin 4 sort normally, they are acerbity bacterium of staphylococcus, streptococcic, third and strong record bacili respectively 4 kinds. Between the bacterium of this second discovery, about 54.4 % can be returned a kind in the center to be these 4 sort.
Scientist discovery, in the skin surface of everybody, have about the bacteria of the bacterium of 3/4 and people skin surface is different, the bacterium that this makes clear surface of each one skin is phyletic very not identical. Research returns discovery, the bacterium on the bacterium on male skin and woman skin also is having notable difference.
"Often live dweller " and " passing traveller "
Making what the scientist feels amazed is, sort meets the bacterium of surface of human body skin produce change inside a few months, those are occupied " control " bacterial change of the position is not big, but those as " passing traveller " the bacterium lies in constant change. "This makes clear, skin itself also has the particular function that eliminate bacterium, the bacterium with a few strong adaptability stayed, other bacterias go again. " professor of a place of strategic importance of lay mines of equestrian fourth · says.
