The article presents results of research of dynamics of morphological, biochemical, haematological and immunological parameters when changing the quantity and species of microorganisms of intestinal microbiocenosis of the rabbits. With the dominance of pathogenic bacteria in rabbit intestinal microbiocenoses, the titer of bifidumbacteria was 10-5-10-4, a decrease in the number of lactobacilli, an increase in the number of enterobacteria, a correlation between the colonization index and the degree of adhesion of bacteria was revealed; an increase in the total number of leukocytes, lymphocytes, erythrocytes, hematocrit, alanine aminotransferase level, aspartate aminotransferase, lactate dehydrogenase, total bilirubin, α-amylase, albumin, alkaline phosphatase, T-killer level, NK cells, concentration of C-reactive protein. We observed a decrease in the concentration of hemoglobin, monocytes, total protein level, T-lymphocytes, T-helpers, B-lymphocytes, phagocytic index, phagocytic activity of leukocytes, NST-spontaneous, NST-stimulated. Dynamics of morphological indicators was characterized by a disorder of the circulation of organs, a predominance of dystrophic and necrotic processes in the tissues and organs of the cardiovascular, respiratory, digestive, excretory system. Infiltration with mononuclear and segmented leukocytes was noted, diffuse lymphoid proliferation of the mucous membranes of the organs, hyperemia, edema, multiple hemorrhages, accumulation of hemorrhagic exudate in the lumen of the respiratory, digestive and urogenital tracts. Observed catarrhal-hemorrhagic inflammation of the gastrointestinal tract; mucous membrane of the stomach, small and large intestines edematic, hyperemic, with hemorrhages, covered with mucus, fibrinous films, with necrotic areas. The signs of acute diffuse interstitial nephritis, characterized by proliferation of connective tissue cells with a predominance of lipoblast and epithelioid cells, are revealed. In the presence of bacterial cells in the lumen of the tubules, the parenchyma of the cortical and medullar layers was marked by microabscesses. Accidental transformation of the thymus was observed, characterized by signs of a circulatory disorder, a decrease in the area of the cortex, the formation of cysts; signs of diffuse hyperplasia of the spleen with necrobiotic changes in the foci of proliferation, reduction of the area of lymphoid follicles, expansion of the area occupied by the red pulp of follicles, hyperplasia of follicles of white pulp with foci of necrosis. Identified multiple bacterial embolism of blood vessels, developed signs of hemorrhagic Diathesis, watched the development of sign infiltrative itch processes.
