| Duan Yunfeng: Doctor of biology of behavior of institute of psychology of the Chinese Academy of Sciences, microbial group learns as postdoctoral as biology informatics, date of popular science public " alvine bacterium and health " author. have CCTV " Chinese good book " " dawn abdomen knows bowel: The caution of alvine bacterium is thought of " .
This is Duan Yunfeng @ momently of Talks show speech video quickly. The bacterium also distributes stand or fall, bacterium group the mood that can affect people not only, return the life and death that can decide people even. This lifetime of the person, the body that wants to have health must with bacterium group concomitant.

On our human body, no matter be,body watch still is inside body, have many microbial, in our factory especially, what have the human body of 80% possibly is microbial, be located in alvine path of the person.
This microbial it is in different position is different, in our oral cavity, in our skin, in our stomach, in our large intestine, small intestine, have those who differ is microbial. This piece of graph can see, different color, or color of avery kind of, represent a kind microbial, in different position, microbial it is different, weight of this a bit biologic can be achieved 1.5 go to 2 kilograms. How many does microbial amount have? Can achieve 14 times square, can say be person oneself cell is decuple.
Someone says, it is 1.3 times of our oneself cell. The amount of these microbial encode gene is then more, it may code millions of gene, the amount of encode gene, it is more than 100 times of amount of gene of oneself of our human body.
What do a bit biology and that this person have to concern? Or the what aspect of our person is it affecting?
Consider to discover now, actually our feeling, our birth, mix our microbial be to have close relationship.
That if microbial enlarge later, everybody is experienced OK and intuitionisticly, resemble what reveal on this piece of graph, if after the microbial enlarge our body watch, it is a kind of such condition. It is thickly dotted the ground distributings to be mixed inside our body inside body, are these then microbial what effect to have?
These are actually microbial it can help us resist bacterium of a few cause of disease, they can form a film, help us resist of those bacterias invade catch. This immune system that a bit biology still can train us, the immune system growth that allows us is perfect. These are additionally microbial the psychosis that still can affect us, even the development of our cerebra.
Microbial with the animal between, it is a kind of accrete relation actually, that what is symbiosis? Symbiosis is mutually beneficial mutual benefit actually, microbial helpful to the person, same person also can is opposite microbial helpful.
In the person's lifetime, microbial attribute dynamic change, think to complete aseptic is in our uterus so, but in last few years consider to discover, in the person's uterus, in its place, existing bacterium. It is for example in amniotic fluid, in placenta, on umbilical cord, have bacterium. Say to be in pregnant this nine month so, fetal with the mother be the trade that has this kind of bacterium all the time actually. Maternal bacterium group affecting this fetal bacterium all the time group.
From after be born, as fetal birth, as produce path, have an inoculation, these are microbial arrive with respect to meeting field planting inside the body of this child. Of course, if this child is analyse palace,produce, below the situation that he produces without experience, maternal bacterium group cannot well field planting arrives inside the child's body, such word, the child his bacterium group cannot normal land development.
Research analyses discovery, if be the child of Caesarean birth, his bacterium group the child growth that development wants to compare normal natural labor wants evening a month. That is to say, if you are Caesarean birth, your bacterium group the child that cannot catch up with natural labor possibly.
Say so, if conditional, can go below the circumstance of natural labor, still need to go natural labor, because of the mother microbial, must have the aid of this kind of process, her ability the bacterium her group deliver offspring. And, the child of natural labor, after he is grown, the risk that produces a few diseases can drop substantially. E.g. allergic, asthma this kind disease, lower inside the child of natural labor, but inside Caesarean birth, its incidence of a disease special tall.
After be born as this child, eat mother milk, eat complementary feed, his bacterium group also meet gradually grow in quantity, until 3 years old are controlled, the bacterium of this child group was close to quite with adult. Go as this child again next nursery school, contact different person, run different food, perhaps travel to each district, its bacterium many groups the gender also can increase gradually gradually. Say so, in the person's lifetime, bacterium group be the dynamic change that is in hour.
After spending year after year, arrived old age, this bacterium of the person group, ebb as his body functionary, his bacterium group also can produce change. Say to be in lifetime so, bacterium group healthy, or bacterium group evenly, the person is met healthy, with respect to meeting balance. If this bacterium group appear below disorder circumstance, the person gets the disease of very special much sort likely.
