Bifidobacterium breve CNCM I-1226, Bifidobacterium infantis CNCM I-227 and Bifidobacterium longum CNCM I-1228 adhere to and competitively exclude pathogenic bacteria from Caco-2 cells. The strains may be incorporated into yogurts, acidified milks and other food compositions.

Immunostimulant products are prepared by adding lysozyme to a culture of L.bulgaricus at a pH of from 4-8 and then incubating the culture to hydrolyze peptidoglycans of cell walls of the bacteria. A suspension containing the lysozyme-treated L.bulgaricus is collected, which is centrifuged to obtain an immunostimulant supernatant. The supernatant may be filtered to obtain an immunostimulant solution, which may be added to a fermented milk, or to a whey, to prepare an immunostimulant product. Alternatively, L.bulgaricus may be cultured and hydrolyzed by lysozyme in a milk product to provide an immunostimulant milk product.
