Estimating the term…
A probiotic lactobacillus was discovered from lactobacilli of the Lactobacillus genus independently isolated from human adult feces. The probiotic lactobacillus was selected from other bacterial strains for: (1) being highly resistant to gastric acid/bile acid; (2) having a high promoting activity on IL-12 production from mouse derived spleen cells and a high Th1/Th2 balance-improving effect; (3) having a high ability to inhibit the production of antigen-specific IgE induced by intraperitoneally administering ovalbumin to BALB/c mice; (4) having a high ability to inhibit the production of antigen-specific IgE induced by orally administering a food antigen to C57BL/6N mice; (5) having a high Natural Killer cell-activating ability; (6) having a high IL-12 production-promoting activity on spleen cells and mesenteric lymph node cells derived from mice immunized with ovalbumin and a high Th1/Th2 balance-improving effect; and (7) having a high ability to suppress eosinophilia induced by a cedar pollen-extracted antigen. This discovery led to the completion of the present invention.
A dietary composition or drink comprising a biologically pure culture of Lactobacillus gasseri OLL2809 deposited under the accession number NITE BP-72 that is in a concentrated form or a dried form, at a content of 0.001% (w/w) or higher, wherein the concentrated form contains 4×1010 cells/g or higher of said Lactobacillus gasseri OLL2809, or the dried form contains 5×1011 cells/g or higher of said Lactobacillus gasseri OLL2809.
