Immune Response of Mice to Orally Administered Lactic Acid Bacteria

Characterization of a Water-soluble Polysaccharide Fraction with Immunopotentiating Activity fromBifidobacterium adolescentisM101–4

“…22 ) In this present study, we found that the soluble immunopotentiator from B. adolescentis M 101-4 was a polysaccharide consisting of Galp, Glvp, and G1cp, and Galf The presence of galactofuranosides (Galfl-and -6Gaif'l-) is unique as the consituents of Gram-positive bacteria. The mutual linkages among these residues and the repeating unit were not completely determined.…”

Effect of probiotics on aspirin-induced gastric mucosal lesions

“…Bifidobacteria has been shown to increase systemic antibody response (35) as well as total IgA production in the intestine (36). In studies of methotrexate-induced enterocolitis in rats, the administration of Lactobacillus plantarum strain 299v increased colonic and ileal levels of sIgA, and reduced mucosal inflammation (37,38).…”

The role of the commensal gut microbial community in broiler chickens

“…Microbial communities, which inhabit the intestinal tract, can stimulate these immune responses and therefore act to strengthen the host's defence mechanisms. Also gut lactic acid bacteria have been shown to have immunostimulatory properties by cell wall components such as peptidoglycans, polysaccharide and teichoic acid (Takahashi et al, 1993;Haller et al, 1999). Therefore, an increased lactic acid bacterial population by means of using prebiotics in the diet of broiler chickens would enhance the natural immune competence ability of the animals by increasing the natural antibody levels, and further to promote the immune defence responsibility.…”
