The human bacterium's distribution map is drawn successfully
Washington, November 8 (Xinhua) a research group of American University of Colorado at Boulder succeeds in drawing out the human bacterium's community's distribution map recently, this achievement is issued on new Science electronic edition. It is reported researcher to 9 healthy volunteer 27 the intersection of bacterium and community of position carry on 3 months -long to observe analyzing thoroughly on one's body. Within 3 months, researchers made bacterium 4 times to sample each volunteer separately, sample, work, go on until volunteer have a bath 1 to 2 hours generally. Researchers use the latest computer technology and genetic technology, draw out the rough distribution map of the human bacterium's community. Because the fungus group is distributed differently between men, the same individual different position fungus group distributes different and the same positions fungus group is distributed to change in different time slots, so it is very difficult to draw out the accurate distribution map. Even so, researchers think whether the fungus group distributes or presents certain mode. The human body is axillary and foot bottom fungus group is distributed and does not change much, may result from these two moist photophobic environments. On several positions of head, for instance positions such as forehead, nostril, ears and hair,etc., the bacterium of a kind of special type has occupied the leading position, body and four limbs are " forcibly occupied " by another kind of different fungus group . Oral cavity the intersection of fungus and group distribute, change even very much little. Researchers are studying the Communist Party of China to find 4200 multi-type bacteria. Director Rob and Knight of the research group says: "The purpose of this research is to find out one group of normal conditions distributed of human fungus of health, offer basis for the fact that the fungus group is distributed to further study the human body under the disease state. " Research say have 100,000 billion bacterium distribute inside and outside human body nearly, among them some bacterium stress in human the intersection of physiological function and the intersection of China and function, can assist the human state of keeping fit effectively. For example, some bacteria can help the human body to construct the immune system, some digest the food of promotion indispensably, others can prevent the pathogen from initiating potential pathological change. Knight thinks, understands the distribution of the human fungus group changes the difference and means great to clinical medical research of future.
