Microbiome of GIT

The intestinal microbiota is a complete collection of bacteria and microbes within the gastrointestinal tract. The GIT contains tens of trillions of microbes, including a wide range of species, the majority belonging to the phyla Firmicutes and Bacteroidetes. The microbiome of the gut contains approximately 3 million genes that are unique. The microbes and the GIT share a symbiotic relationship between each other. The microbes help to get energy from food and synthesis of vitamins and amino acids, thereby offering protection from pathogens. Damage to the intestinal microbiota homeostasis is found to be associated with inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, food allergies, type 1 diabetes, type 2 diabetes, cancer, obesity, and cardiovascular disease.
