This paper sought to investigate the modifies of inulin and Bacillus clausii on the lipopolysaccharides (LPS) inducing oxidative stress signaling pathway in the endotoxemic rat model.


Wistar albino male rats (n = 36), divided into six groups, were formed randomly in the following stages: the control group; the prebiotic group (Inulin; 500 mg/kg); the probiotic group (Bacillus clausii; 1x109 CFU); the LPS group (1.5 mg/kg) as the endotoxemic model; the prebiotic group + LPS; and the probiotic group + LPS as treatment groups.


The reactive oxygen species (ROS), advanced oxidation products of protein (AOPP), thiobarbituric acid reactive substances (TBARS), total oxidant status (TOS), oxidative stress index (OSI), and myeloperoxidase activity (MPO) levels increased in LPS-induced toxicity. Prebiotic treatment decreased LPS-induced hepatotoxicity on rat liver as observed in the decrease in the levels of oxidative stress parameters, such as ROS, TBARS, TOS, and OSI. The effect of the probiotic treatment on the ROS, AOPP, TOS, OSI levels was not statistically significant. However, it was determined that probiotic application was effective in the TBARS, TAS, and GSH levels. When the biochemical results of the prebiotic and probiotic treatment applications were compared, it was found that the prebiotic treatment was more effective on oxidative stress parameters (ROS, TBARS, TOS, and OSI). In addition, the histological damage score and MPO-staining results of the prebiotic treatment group were found to be more effective than the probiotic group.


In this first study, where inulin and Bacillus clausii spores are used against liver damage caused by LPS, inulin provides much more effective protection than Bacillus clausii spores.
