Abstract: The in vivo immunostimulation function of Bifidobacterium BBMN01 from macrobian were studied in this paper. Mice in the treatment group were perfused by the living bacteria BBMN01in different dose continuously for 3 weeks. The tests for delayed type hypersensitivity(DTH), the peritoneal macrophage phago-function for chicken red blood cells, total hemolytic complement (HC50), and lactic acid dehydrogenase(LDH ) were taken to demonstrated the effect of BBMN01 living bacteria on cell-mediated immune function, humoral immune function, macrophage phagocytosis function and natural killer cell’s activity of mice. In comparison with control group, the lymphocyte trasformation rate, phagocytosis of macrophage and the NK cell’s activity significantly increased in all those treatment group, and the HC50 value of the mice significantly increased in high and medium dose group.

Key words: Bifidobacterium, in vivo, immunostimulation activity
