" The saliva bacterium " As unique as fingerprint Everybody differs
" wire " the intersection of magazine and report according to U.S.A., " the the intersection of genome and research " magazine deliver article claim recently: There are different microbial bacteria of 600 multi-type in people's saliva, and these bacteria vary with each individual. Whether people live or live on both sides of the earth separately, their saliva bacteria may be different. Just as what all mothers in the world said like that: All children are unique, have unique ability, natural gift Even unique oral cavity bacterium.

Leipzig of Germany (Leipzig) Mark - Stone and Kern (MarkStoneking) that Max - Plonk association evolves in the research institute of anthropology It is one of the co-authors of this thesis, he says: "It is a surprising discovery for us. We are expected if the investigation of paying all different eating habits in the world with people of different culture, will also find some new differences. " Scientist's saliva sample from 120 people of abstraction of different areas such as North America, South America, Europe, Asia and Africa,etc. separately, through arranging in an order and analyzing the gene in the sample of saliva, they have already recognised 101 kinds of known bacteria, in that 39 kinds have never been found in the oral cavity. In addition, researchers also find 64 kinds of unknown bacteria at least. Stone and Kern says: "We should measure the difference of the saliva in the world, because this will be unprecedented research. "

Oral cavity microorganism very much loud difference stores in composition in because of the change of individual, and is free of any regional structure. Two persons from Louisiana state and a Bolivian and one of South African's oral cavity bacteria have a very great difference. Because there is no connection on any geography, science hopes to understand whether population relates to oral cavity microorganism. Some other is studied through analyzing to residents' viscera microorganism of different areas that has already reproduced the distribution and migration of ancient population. But such research needs to carry on the stomach biopsy to the respondent, so Stone and Kern and his colleagues hope to measure and organize the inspection instead of the stomach through the saliva bacterium.

Stone and Kern says: "If we can distinguish the change of the particular bacterium, then we still hope to find out the connection between them. This is exactly what we make great efforts to realize now too. This result of study will be helped in the range of setting up a healthy individual saliva bacterium too, this will be very important to the disease diagnosis in the future. " Ruth - thunder (RuthLey) of the university of Connell Though has not participated in this research, he says: "The saliva sample is a sample drawn very easily, can not find out the saliva, that will be very valuable. "

The signal coming to light in people's microorganism whose body grow is very important. Noah - Filler (NoahFierer) of Colorado university Had led the research group to find that had 150 kinds of different bacteria on the centres of the palm of people on average last year, he says: "This research has verified too that really there are a large number of different types of microorganisms in our body, we are basically ecosystems of a microorganism that can move. "

In fact, the bacterium exceeds human normal cells in the human body, the scientist estimates on the human body and the microorganism surviving within the body is more than 10 times of human body's normal cell. Filler is said: "A lot of people hear the news may give a start, have many a harmless one even some or beneficial one totally in microorganism these. For example, some viscera bacteria can stimulate the enhancement of the immune system, help us to digest the carbohydrate and fat, and can formate necessary vitamin for us. These microorganisms have been growing and evolving with us all the time, and they depend on the human health. In many situations, we do not even know their name. "

In 2007, the state-run hygiene research institute of U.S.A. determines to invest 115 million dollars to use and catalogue the record for these a large number of microorganisms, make people understand this bacterium's family to some extent. The human microorganism's group's project of the result was established last year. Have launched similar research in Europe and Asia successively. A better understanding will mean great to future human health. For example, one the latest one discovers: There is different bacterium group in the viscera of fat people and thin people. When fat people reduced weight, the bacterium group in their viscera changed too, closer to the bacterium group in the thin people's viscera more. Removing those can help the fat card in the world of treatment when causing fat bacterium group. Other the intersection of viscera and bacterium also will cause cancer, asthma, one's own immunity ill, etc while being unbalanced. (sharp point dose /compile)
