Abstract

Lactobacillus gasseri SF1183 belongs to a subpopulation of bacteria tightly associated to the human ileal epithelium. Cells of SF1183 survive and grow in simulated intestinal and gastric conditions, have a strong antimicrobial activity against Gram-positives and Gram-negatives and secrete molecule(s) sensed by human intestinal cells. We report that the oral administration of SF1183 cells had a protective effect in a murine model of DSS (Dextran-Sulfate-Sodium)-induced colitis. The analysis of the intestinal microbial composition indicated that several bacterial genera were differently represented in the intestine of DSS-treated animals. An overall similar alteration was observed in the microbiota of DSS-treated animals that received SF1183, suggesting that the beneficial role of the probiotic was not played through a reshuffling of the intestinal flora. Based on our in vivo data we propose the SF1183 strain of L. gasseri as a new anti-inflammatory probiotic, potentially useful as a therapeutic agent for the treatment of IBDs.
