Definition

A probiotic composed of a strain of the Gram-positive, naturally-occurring bacterium Lactobacillus, with potential antimicrobial, immunomodulatory and protective activities. Upon oral administration of the Lactobacillus probiotic BSL_PS6, the Lactobacillus strain may improve digestion and help maintain adequate colonization of the gastrointestinal (GI) tract by modulating the composition of the normal microflora. During colonization of the GI tract, this bacterium adheres to human intestinal epithelial cells, and activates intestinal epithelial proliferation. This promotes the formation and maintenance of a protective barrier, thereby preventing the attachment of harmful pathogens. The Lactobacillus produces an acidic environment that is unfavorable for pathogens, thereby further protecting the intestinal mucosa against pathogen-induced damage and a loss of integrity of the intestinal mucosal barrier. Dietary supplementation with this bacterium may decrease intestinal inflammation and enhance intestinal immune responses.
