The composition of intestinal microorganisms
The core research objective of intestinal microbiota analysis is to systematically depict the composition and functional map of the vast microbial community within the human intestine, including bacteria, fungi, and viruses. The high degree of correlation lies in the fact that these microorganisms deeply participate in various physiological processes of the host, from digestion and absorption to neural regulation, by regulating immunity, metabolizing nutrients, and maintaining the intestinal barrier. Therefore, analyzing their structural characteristics and dynamic changes is not only crucial for understanding the mechanisms of various complex diseases such as inflammatory bowel disease, colorectal cancer, and metabolic disorders, but also holds great potential to provide new biomarkers and targets for the early warning, prognosis assessment of diseases, as well as the development of precise treatment plans such as probiotics, dietary intervention, and fecal microbiota transplantation.
