It is intended to provide a lactic acid bacterium selected from the group consisting of Lactobacillus ONRIC b0239 (FERM BP-10064) and Lactobacillus ONRIC b0240 (FERM BP-10065); and a composition (in particular, a composition in the form of a food, a drink or a drug) containing the lactic acid bacterium and having a mucosal immunopotentiation effect. The above-described lactic acid bacterium and the composition containing the same can exert an excellent mucosal immunopotentiation effect and, therefore, are useful in strengthening the biological defense system. |
