In humans beings, the gut microbiota has indeed the largest numbers of bacteria and the greatest number of species compared to other areas of the body. In humans, the gut flora is in fact established at one to two years after birth, by which time the intestinal epithelium, as well as the intestinal mucosal barrier that does secrete, have co-developed in a way that is tolerant to, and even supportive of, the gut flora and that also does provide a barrier to pathogenic organisms.
The relationship between some gut not indeed merely commensal (a non-harmful coexistence), but rather a mutualistic relationship. Some human gut microorganisms do indeed benefit the host by fermenting dietary fiber into short-chain fatty acids (SCFAs), such as acetic acid and butyric acid, which are then of course absorbed by the host.
Intestinal bacteria also does play a role in synthesizing vitamin B and vitamin K as well as metabolizing bile acids, sterols, and xenobiotics. The systemic importance of the SCFAs and other compounds do produce hormones types and the gut flora does itself appear to function as an endocrine organ, and dysregulation of the gut flora has indeed been correlated with a host of inflammatory as well as autoimmune conditions.
The composition of human gut macrobiotic changes over time, when the diet changes, and as overall health changes. A systematic review from 2016 examined the preclinical and small human trials that have been conducted with certain commercially available strains of probiotic bacteria and identified those that had the most potential to be useful for certain central nervous system disorders.
Flora is the scientific term for a group of plant or bacteria life, which is typical to a particular area. It is often contrasted with the term ‘fauna’, which is used to describe the animal life of the same particular area. In the area of health as well as medicine, flora is the term that is made use of to describe the microorganisms that exist on or within the human body, such as the gut flora or the skin flora. When talking about flora in the context of the human body, the term does refer to bacteria, yeast, and other fungi.
Gut flora actually refers to the world of microorganisms, which is predominantly bacteria, that does populate our intestines. Research has rather focused on trying to understand the role that the gut flora actually plays as far as human health is concerned. A variety of names are made use of for it such as:
• Gut bacteria
• Intestinal flora
Gut indeed play an important role in both health as well as vulnerability to disease.
Babies are indeed born with intestines that are rather believed to be either completely or mostly sterile. As they do go through their mother’s birth canal, they are rather exposed to the microorganisms of her vagina, which is the origin of the population of the microbiome. The microbiome is in fact further populated by environmental exposure and intake of Improve breast milk, formula and ultimately food. These are the factors that populate the microbiome of babies that are born via cesarean section.
