Mechanisms for the prevention of intestinal infections

In the complex micro-ecosystem of human intestinal intestine, intestinal intestines play an essential role in the multi-role mechanism for the prevention of intestinal intestine, which is indispensable for the maintenance of intestinal health. First, intestinal prophylactic bacteria regulate the intestinal community balance. Under normal conditions, the intestinal prophylogenesis, mesmophiles and fungi are in a dynamic equilibrium. When the prophylactic bacteria are in sufficient quantities and are well active, they can inhibit the growth and reproduction of harmful bacteria by competing for nutrients and sticky points. For example, albino and acidic fungi are capable of forming a biological barrier on the intestinal mucous surfaces to prevent the planting and intrusion of harmful bacteria such as cobuli, salmonella, and hard-to-feed bacteria. They can also produce anti-bacterial substances, such as bacterial and hydrogen peroxide, which can directly inhibit or destroy the fungs, thereby reducing the damage to the intestinal mucous membranes and the risk of entericitis. Second, intestinal prophylactic bacteria helps to enhance intestinal barriers. The intestinal barrier consists of a mechanical barrier, a chemical barrier, a immune barrier and a biological barrier, many of which are reinforced by the fungi. In the case of mechanical barriers, the prophylactic bacteria can promote the growth and separation of intestinal skin cells and maintain the integrity of intestinal mucous membranes. For example, some of the prophylactic bacteria can stimulate intestinal epipelagic cell scrawl, and the thickening of the mucous layer can further prevent contact between the fungus and the intestinal mucous membrane. From the point of view of the immune barrier, the fungi regulates the activity of intestinal immune cells. They stimulate the development of lymphocyte-related lymphoma in the intestinal tract, promote the genre of immunoglobin A (Iga), and Iga can form an immunoprotective layer on the intestinal mucous membrane surface, integrate and remove pathogens in the intestinal tract, enhance intestinal local immunity and effectively prevent intestinal inflammation caused by pathogens. Furthermore, intestinal fungi has the capacity to regulate intestinal immune response. Within the intestinal tract, the prophylactic bacteria can interact with intestinal skin cells and immunocellular cells and induce immunosuppressive formation. When intestinal tracts are irritated or antigens are invaded, prophylactic bacteria can inhibit excessive immunisation and prevent inflammation responses from spiralling out of control. They achieve this by regulating the cytogen genre, e.g. reducing the presence of the agonist factors, e.g. white cytin – 6 (IL – 6), cancer cause of death – alpha (TNF – alpha), and increasing the presence of antiinflammatory factors, e.g. white cytin – 10 (IL – 10). This fine-tuning of the immune response allows the intestinal tract to maintain a moderate immune response in the face of challenges and to avoid inflammation due to inflammation. In addition, intestinal fungi can be involved in intestinal metabolic activities and indirectly prevent intestinal inflammation. They produce short-chain fatty acids (e.g., acetic acid, acrylic acid, butic acid, etc.) that are not easily digestible, such as fermented food fibres. Short-chain fatty acids not only provide energy for the growth and repair of intestinal skin cells, but also have inflammatory properties that reduce inflammation levels in the intestinal tract, maintain environmental stability in the intestinal tract and reduce the incidence of intestinal inflammation. Based on the above, intestinal prophylactic bacteria play a crucial role in the prevention of entericitis by regulating the balance of intestinal strains, enhancing the intestinal barrier function, regulating the immune response and participating in intestinal metabolism. Maintaining the preponderance of intestinal fungi, whether through dietary ingestion of foods (e.g. yogurt, fermentation, etc.) and appropriate supplementation of fungi formulations, is of clinical importance and public health value for the protection of intestinal health and the prevention of intestinal inflammation. As in-depth studies of intestinal prophylactic bacteria continue, their application to intestinal inflammation prevention and intestinal health management will also be more promising.
