Results of study of microecological disorders in oral cavity of patients with non-specific ulcerative colitis (NSUC) and Crohn’s disease (CD) and control subjects (patients with hypertension). Condition of mucosa was assessed on the basis of morphological data and electrophoretic mobility of cell nuclei, whereas structure of microbiocenosis and metabolic activity of microflora — on the basis of saliva bacterial culture and contents and profile of volatile fat acids in it. Detection rate of negative charge of the cell nuclei (decrease of functional activity of epithelium) was significantly higher in patients with NSUC and CD (66.6%) compared with controls (10%). This fact was directly related with hypercolonization of oral cavity by Gram-negative microflora. Lesions of mucosa which are characteristic of NSUC and CD and determined by pathologic immune mechanisms correlated with quantity of pathogenic microflora (Staphylococcus aureus and Candida). Marked differences of chromatograms’ patterns were observed in patients with NSUC and CD indicating the suppression of anaerobic microflora in patients with CD and hypercolonization of oral cavity by anaerobic microflora in majority of patients with NSUC.
