10 seconds of kissing, 80 million bacteria exchange, and kissing produces a couple phase?
4hw.org: in fact, there was a common sense of scientific kissing in the early days. Relevant research shows that two people can exchange 80 million bacteria groups when kissing. Recently, a video detonated the network. Because of the bacteria groups exchanged by kissing, there was a couple phase? Let's take a look at it together!
Recently, a video on the social platform detonated the network. In the video, Yin ye, CEO of Shenzhen Huada gene Co., Ltd., a point of view triggered many netizens' discussion. He said in the video: 'if we kiss for ten seconds, we exchange 80 million colonies. Understand how husband and wife form? The flora is beginning to converge. '
Netizens have exclaimed, "rising posture!", "looking for good-looking people to kiss", "male ticket is too ugly to break up" and so on, but is it true?
Colonies make lovers grow more and more alike? It's too early to make a conclusion
The so-called conjugal phase exists all over the world. Due to different perspectives of researchers, the formation of conjugal phase is also complex and diverse. There are both psychological analysis and visual discussion, and it is generally believed that the most reasonable explanation is from the perspective of microorganisms.
Husband and wife live together for a long time, with the same diet structure, similar work and rest time. Coupled with the intimate husband and wife behavior, the original bacterial micro ecological environment of the two people is becoming more and more similar. At the same time of colony convergence in the two human bodies, the character, behavior habit and even physiological state of the two husband and wife are affected and more and more similar, which leads to what people often call "husband and wife phase".
Zhu Baoli, a researcher at the Institute of Microbiology of the Chinese Academy of Sciences and director of the center for environmental microbial genomics, thinks that at present, this view is only conjecture that "husband and wife" are related to the microorganisms in the human body, but it has not been fully proved.
There are also views that the reason why Europeans and Asians look different is not only because of genes, environment and other reasons, but also because of the bacteria in the body. However, they are only speculating, and there is no substantive evidence. It is too early to make a conclusion.
The saying of "husband and wife" is still in the speculative stage, so it is not sure that it is the effect of bacterial convergence, but the effect of bacterial convergence on the body has been confirmed. Here's an example for us.
At the end of 2015, science published an article on the efficacy of intestinal microbial immunoagents in the treatment of cancer. Two groups of mice from different places were used, one from Jackson lab and the other from Taconic farm. The intestinal microflora of the two groups were different. The same skin cancer cells were implanted into the dermis of two groups of mice, and the growth of skin cancer was observed.
After a period of time, it was found that the skin cancer cells in the mice from Jackson lab grew slowly and were inhibited to some extent; the cancer cells in the mice from Taconic farm grew very fast. It has been proved that there are bifidobacteria in the mice of Jackson lab and very few in the mice of Taconic farm. Bifidobacterium can promote the effect of immunotherapy.
Later, the researchers mixed the two groups of mice, and after a period of time, they found that the tumor growth state of the two groups of mice tended to be the same. In mice from Taconic farm, cancer cells grew slower, while in Jackson lab, they grew faster.
It is concluded that the bacteria in the body of the two groups of mice will tend to be the same after mixed feeding, and the colony convergence will have an impact on the body of the two groups of mice.
Researcher Zhu Baoli said: 'this is the result of the experiment. If it's a person, two people live together for a long time, and the flora in the body has a similar trend, then two people will also have some physiological similarities, such as the physical state, the probability of getting disease and so on. However, the effect in the population is not very obvious, because the experimental mice will eat feces each other, so the number of bacteria spread is more, but the bacteria spread between people are spread by eating together, intimate behavior and a small amount of air, so the amount of bacteria spread will be less. '
The level of bifidobacteria in people of all ages.
Immune system provides guarantee for colony convergence
Since the human body will spread each other's colonies, and the convergence of the colonies will indeed have an impact on the physiological state of the human body, then people's concerns will follow: 'boyfriend is too ugly, to break up, or it will infect & hellip; & hellip;' some people also worry that if the colonies are safe in each other's body, but after entering their own body, how can they not adapt to it?
Is the process of bacterial exchange really possible to bring colony that is not conducive to the health of the other party? In this regard, from the perspective of pathogenic bacteria and symbiotic bacteria, Zhu Baoli answers: "generally speaking, the bacterial convergence we call is considered from the perspective of symbiotic bacteria, and the colony that can bring disease to the other party is pathogenic bacteria or pathogenic bacteria. For the pathogen, there will be antigens in the body to suppress or kill it. If the pathogen is transmitted to the other party in the process of flora exchange, the other party can kill the pathogen as well. '
In addition to killing pathogens and pathogens, the human body has a 'white list' of colonies.
In fact, human beings and microorganisms are coevolutionary. Human beings can't live without bacteria and bacteria can't live without human beings. The bacteria here refer to the bacteria in the human body and the bacteria released by the human body into the environment. The result of coevolution is that some bacteria, even if not in the human body, will be recognized by the human immune system as bacteria that are allowed to enter the body, and in principle (based on scientific hypothesis) will not produce antibodies. These bacteria are recognized by the immune system and can coexist safely with the human body to achieve a certain balance. 'said Julie.
The immune system can help us identify colonies.
Newborn should get enough beneficial colony
In addition to the colony can affect the physical state of the couple, it also has a huge impact on the next generation. The traditional idea is that children are very fragile at birth, so they should be kept away from bacteria and protected well. In fact, this idea will harm children instead.
According to juboly, the role of the flora is not only likely to affect the 'conjugal phase' in adulthood, but also affect a person's physical state. For newborns, how much bacteria they get and what bacteria they get are very important to their children's health.
The main sources of bacteria after birth are: during birth, breastfeeding, bacteria in family environment, bacteria in food. The bacteria obtained in the process of growth are very important for infants. If we get symbiotic bacteria that should exist in the human body, children can activate their immune system, and they will grow up in a more optimistic state. However, if the flora acquired by the newborn is bacteria such as opportunistic pathogens, health problems may occur during the growth process, such as allergic autoimmunity, asthma, etc.
For newborns, how much bacteria they get and what they get are very important to their health.
"According to the existing scientific hypothesis, a person can get 350 or more symbionts in the intestine after birth, and the health of his immune system should be normal," said juboli. If the newborn does not get enough bacteria after birth, its health status is uncertain. Especially half a year after the birth of the child, the body's immune system is very important for the identification of bacterial species. Suppose that during half a year of the birth of a newborn, the body gains harmful bacteria and occupies the intestinal tract, the immune system in the body will produce a contradiction. Although there is no clear evidence for this statement at present, the academic community generally recognizes this mechanism. '
