Cross-correlation analysis of the Desulfovibrio growth parameters of intestinal species isolated from people with colitis

Abstract

Sulfate-reducing bacteria can be involved in inflammatory bowel disease. Cross-correlation parameters of their metabolic process in the gut have never been reported before. The aim of the research was to statistically (cross-correlation) evaluate the parameters of growth (biomass) of Desulfovibrio species from colitis people and healthy as well as to investigate the change in dissimilatory sulfate reduction of these bacterial strains. The microbiological, biochemical, chemical, and statistical methods were used in the research. The cross-correlation analysis indicates that the strains isolated from people with colitis shifted to the right side of Y axe by biomass accumulation, sulfate consumption, lactate oxidation as well as hydrogen sulfide and acetate production, compared with the strains isolated from healthy individuals. Different percentages were observed in shifting to the right side of Y axe: biomass accumulation 26%, sulfate consumption 1.5%, sulfide production 5%, lactate oxidation 3% and acetate production 12%. The biomass accumulation of intestinal sulfate-reducing bacteria and their hydrogen sulfide production are the main factors in inflammatory bowel disease development, including ulcerative colitis. Acetate production showed lesser influence while sulfate consumption and lactate oxidation are negligible factors in the inflammatory bowel disease.
