[Studies of changes in human intestinal micro-biocenosis in health and in disease].

: The paper contains the generalized many-year research conducted by staff of the chair for microbiology (including virology and immunology) aimed at describing the universal principles related with forming an inter-individual diversity of gastric-and-intestinal micro-biocenosis. The research demonstrated a high dependence of qualitative and quantitative parameters of the analyzed biotope on various-genesis factors. It was established that the nature of violations in the gastric-and-intestinal micro-biocenosis is not dependent on peculiarities of an influencing pathogenetic factor, and its difference is related only with quantitative and qualitative (specific) changes in the microbial composition. The marked feature makes it possible to regard the gastric-and-intestinal micro-biocenosis as a non-specific indicator of the condition of a macro-organism and that of the environmental quality.
