Abstract

The present invention pertains to novel microorganisms of the genus Bifidobacterium, that are useful in preventing diarrhea brought about by pathogenic bacteria. In particular, the present invention relates to the use of said microorganisms for the preparation of an ingestable support and to a composition containing the same.

Claims

1. An ingestible composition capable of preventing colonization of bacteria causing diarrhea comprising a biologically pure culture of Bifidobacterium selected from the group consisting of Bifidobacterium longum CNCM I-2169 and Bifidobacterium longum CNCM I-2170, wherein the composition is a food composition comprising about 10⁵ cfu/g to about 10¹² cfu/g of the Bifidobacterium culture.

2. An ingestible composition capable of preventing colonization of bacteria causing diarrhea comprising a biologically pure culture of Bifidobacterium selected from the group consisting of Bifidobacterium longum CNCM I-2169 and Bifidobacterium longum CNCM I-2170, wherein the composition is a pharmaceutical composition comprising about 10⁷ cfu/g to about 10¹² cfu/g of the Bifidobacterium culture.

3. An ingestible composition capable of preventing colonization of bacteria causing diarrhea comprising a biologically pure culture of Bifidobacterium selected from the group consisting of Bifidobacterium longum CNCM I-2169 and Bifidobacterium longum CNCM I-2170, wherein the Bifidobacterium culture ranges in concentration from about 1×

10⁶ cells/ml to about 5×

10⁶ cells/ml.
