To evaluate the efficiency of the probiotic strain Lactobacillus plantarum LS/07 in dextran sulphate sodium (DSS) induced acute colitis selected biochemical (activity of β-glucuronidase), microbiological (counts of lactobacilli and coliforms), and immunological (IL-6, IL-8, IL-13, NF-κB, MPO) parameters were assessed. Sprague-Dawley rats were divided into groups: Control, Acute colitis, and Probiotic. Acute colitis was induced using 5% DSS in drinking water for 7d. DSS induced an inflammatory process in the colonic tissue, increased the activity of β-glucuronidase (p<0.001), increased the counts of coliform bacteria and decreased lactobacilli counts (p<0.05), and activated the production of the measured parameters (NF-κB, MPO, IL-6, IL-8) except of IL-13. Lactobacillus plantarum LS/07 in the diet alleviated the DSS induced inflammatory process by inhibiting the production of IL-6, IL-8, the activities of NF-κB and MPO, and stimulated the production of IL-13. The probiotic reduced the activity of β-glucuronidase (p<0.05), increased lactobacilli counts and decreased coliform bacteria. These results indicate that di­etary intake of Lactobacillus plantarum LS/07 suppressed the expression of markers playing an important role in the inflammatory process. We conclude that the anti-inflammatory properties of Lactobacillus plantarum LS/07 makes its suitable for the prevention or treatment of colitis.
