In other words, the ancestors of contemporary earthlings are not entirely human, but some are bacteria and viruses.
Don't panic, these microbial gene fragments entered the human genome bit by bit through one accidental gene exchange event after another in the long process of human evolution.
As for the impact on the human body, it is still unclear. However, in any case, they have existed in the human genome for at least hundreds of thousands of years, which is also your ancestral chromosome. If you pass them on, if you know your life, you can live with a smile.
Although it has nothing to do with the genome, scientists are paying more and more attention to those microorganisms that are still alive and kicking in the human body.
For example, a recent paper published in Nature Medicine found that when inflammatory bowel diseases such as Crohn's disease and ulcerative colitis occur, the intestinal flora will also change significantly. Using oral probiotics such as Bifidobacterium to regulate intestinal flora has therapeutic effect on many intestinal diseases, which has been the basic operation in gastroenterology and pediatrics for many years.
There are many kinds of bacteria in the intestine that can help digestion.
What is skin microecology?
As we all know, skin is also an important place for human microorganisms to survive. About 74%~80% of skin microorganisms are bacteria (mainly propionibacterium, staphylococcus, Pseudomonas, etc. ), 5%~ 10% is fungi (mainly malassezia), 10%~20% is virus (phage). Among them, the most concerned is the role of various bacteria in skin diseases.
Pores blocked by sebum and dead skin cells can promote the growth of some bacteria, eventually leading to redness and inflammation accompanied by papules?
Taking the intestine as an example, we know that regulating local microecology can treat and prevent diseases in related parts. Can this experience be applied to the skin?
Imagine that if we can adjust the micro-ecology of the skin surface by some means, so as to realize the treatment of skin diseases, and even achieve the effects of whitening, relieving itching and anti-aging, it will surely be a great revolution in the field of dermatology in understanding and treating diseases.
Fortunately, more and more research results illuminate the way of human beings in skin microecological regulation.
