Intestinal microecology in some systemic connective tissue diseases

In patients with systemic connective tissue diseases were studied. The species structure intestinal microflora was characterized by decrease of dominating status of anaerobic bacteria and increase of role of opportunistic bacteria. The number of Lactobacillus decreased significantly. Bifidobacterium and Bacteroides was also decreased in number while their detection rate did not change. Opportunistic bacteria with hemolytic activity acquired greater significance in the forming of patients' intestinal microbiocenosis. Significant increase of Staphylococcus and opportunistic Enterobacteriaceae detection rate and density of intestine colonization was detected. Colonization of the intestine by S. aureus was revealed. Comparative analysis of the qualitative and quantitative structure of the intestinal microflora in patients with systemic lupus erythematosus and systemic scleriasis revealed similar patterns. However, colonization of the gut by opportunistic intestinal bacteria, Candida and microorganisms with hemolytic activity was more frequently observed in patients with systemic scleriasis.
