Lactobacillus - lactic acid bacteria, have the greatest physiological significance in the biocenosis of the microflora of the oral cavity. The active life of lactic acid microorganisms creates an environment favorable for the development of normal microflora. Due to the formation of a large amount of lactic acid during the life of lactobacilli, they inhibit the growth (are antagonists) of other microorganisms: staphylococci, Escherichia coli, dysenteric rods, and viruses, which has been proven in many different scientific studies. Lactobacilli are non-pathogenic microorganisms and therefore do not cause disease.
Microflora of the oral cavity
The active life of lactobacilli creates a favorable environment for the development of normal microflora. The antagonistic activity of normal microflora with respect to pathogenic and opportunistic bacteria and viruses is manifested due to the synthesis of bactericidal substances (nisin, diplococcin, acidophilus, lactocidin, lactolin, log, mucin, etc.), metabolites with antibiotic activity (hydrogen peroxide, etc.). ), organic acids.
Due to the normal microflora, endogenous synthesis of biologically active compounds (volatile fatty acids, defensins, hormones, neuropeptides, vitamins of group B, PP, K, C) takes place, the synthesis and absorption of vitamins D and E, folic and nicotinic acids received in the body improve food.
The action of lactobacilli
The antiviral effects of lactobacilli can be realized in various ways. Lactobacilli can directly bind to the virus and prevent its attachment to the mucous membrane. Lactobacilli contribute to the regeneration of the mucous membranes: intestinal mucin inhibits the reproduction of viruses. The antiviral effect of lactobacilli is associated with their ability to produce antimicrobial peptides, dehydrogenases, NO. The ability of lactobacilli to modulate the functions of epithelial cells, dendritic cells, CD4 +, CD8 + lymphocytes, NK cells has been shown.
