<；P>；PROBLEM TO BE SOLVED: To provide Lactobacillus having human-originated immunostimulative action expressing IgA-inducing activity, products added with and containing the same and a method for producing the products. <；P>；SOLUTION: The IgA-inducing activity was evaluated on Lactobacillus 53 strain in human-originated Lactobacillus using mouse Peyer's patch cells. The result shows that Lactobacillus gasseri expresses the IgA-inducing activity and, especially Lactobacillus gasseri A10-02 strain (FERM, P-21399) has 6.4 relative value (about 5-7 times of other Lactobacillus strains) of the IgA inducing activity. Based on the fact, the Lactobacillus strain has been found to be Lactobacillus having the immunostimulative action, a product containing the same and a method for producing the products containing the same as an additive are provided. <；P>；COPYRIGHT: (C)2008,JPO&INPIT
