A large number of bacteria are distributed on the surface of our skin, gastrointestinal tract, oral cavity, respiratory tract, genitourinary tract, feces and other parts. Among them, gastrointestinal bacteria are various and numerous, accounting for about 80% of the total amount of human microorganisms. There are more than 1,000 kinds of bacteria in the intestinal tract of healthy adults, and the number is as high as 100 trillion, which is 10 times the total number of cells on our human body: there are more than 1,013 bacteria in the human gastrointestinal tract, and there are 400 billion symbiotic bacteria in every gram of dry feces. . Therefore, you are not an independent organism, but a community that is interdependent and symbiotic with the flora. probioticseverything.com

Gastrointestinal commensal bacteria can be divided into three categories:
(1) Membrane flora (deep layer), also known as probiotics, are close to the mucosal surface, mainly bifidobacteria and lactobacilli, which are beneficial and harmless to the body and are indispensable to the human body. Under normal circumstances, they are the dominant flora and have protection , nutrition, immune regulation, etc.;
(2) Opportunistic pathogenic bacteria (surface layer), which can swim, also known as Coelobacterium, are non-dominant flora, such as Enterococcus, Enterobacter, etc. It is harmless when the human flora is balanced, but when the flora is out of balance, it will attack the human body and cause disease;
(3) Pathogenic bacteria (middle layer) are harmful to the human body and can cause diseases, such as Proteus, Pseudomonas and Clostridium perfringens. probioticseverything.com

The concept and causes of intestinal dysbiosis
The human microecological imbalance is: “The microecological balance between the normal microbiota and between the normal microbiota and the host changes from a physiological combination to a pathological combination state under the influence of the external environment.” Simply put, the human microecological imbalance It is the imbalance between bacteria and bacteria in the body, or the imbalance between bacteria and the body, or the imbalance between the unity of bacteria and the body and the external environment, which makes the human body change from a normal situation to a diseased state. probioticseverything.com

The causes of microecological imbalance are probably as follows:
Radioactive radiation: radiotherapy, chemotherapy, x-rays and certain radioactive substances
Overuse of antibiotics: most patients are caused by long-term irrational use of antibiotics
Surgery: including surgery, plastic surgery, intubation, and all methods and measures that affect the host’s physiological and anatomical structure, are conducive to the translocation and transfer of normal flora. Therefore, surgical treatment measures play an important role in the inducing factors of microecological disorders. Other factors: including iatrogenic factors, the use of immunosuppressive agents, cytotoxic substances and hormones, all of which can reduce the immune function of the body. For example, anaerobic bacteria such as Bacteroides fragilis and Peptococcus in the normal intestinal flora can often Become opportunistic pathogens and cause endogenous infection. probioticseverything.com
