SOCIETY OF ENVIRONMENTAL NICHE: ORAL CAVITY OF THE HEALTHY CHILDREN

In recent years, saliva is increasingly being used as a diagnostic fluid for the evaluation of various biological parameters, namely, the levels of activity of the information signal molecules of the metaorganism — the immune-neuroendocrine nature, but less often the metabolites of the microbial com...

description	In recent years, saliva is increasingly being used as a diagnostic fluid for the evaluation of various biological parameters, namely, the levels of activity of the information signal molecules of the metaorganism — the immune-neuroendocrine nature, but less often the metabolites of the microbial community and the structure of the bacterial society. The paper assesses the microbial society of the oral cavity (saliva/smear from the surfaces of the microbiota) healthy children in order to create microbial images of «health» — control that can be used in the study of the microbial community in the development of local and/or systemic pathophysiological processes, including infections, in the child’s body.
