To investigate the intestinal colonization capability of a dairy Propionibacterium strain and evaluate its effects on host lipid metabolism and immune system activity.
Mice receiving conventional or high-lipid diets were administered dairy propionibacteria in skim milk via drinking water for 7 days across 5 dietary groups.
Bacterial counts were monitored in faeces and intestinal tissue sections during treatment and 1 week after cessation.
Host serum lipid parameters (total cholesterol, HDL, LDL, triglycerides) and phagocytic activity of peritoneal macrophages and the reticuloendothelial system were measured.
Propionibacterium successfully colonized the gut through mucosal adhesion and persisted in high numbers 1 week after discontinuation.
Bacterial administration counteracted diet-induced hyperlipemia by favorably altering circulating cholesterol and triglyceride levels.
Phagocytic activity of peritoneal macrophages and the reticuloendothelial system significantly increased by day 7 of treatment before returning to baseline on a conventional diet.
