Abstract: The present invention generally relates to the field of probiotic bacteria. In particular, the present invention relates to natural derivatives of the Lactobacillus johnsonii strain CNCM I-1225 with improved properties. For example, the present invention relates to a natural derivative of the Lactobacillus johnsonii strain CNCM I-1225 that is deficient in D-lactic acid production and exhibits an improved viability during product storage.

Abstract: A Bifidobacterium comprising a genome that is customized so as to lack an operable functional gene is disclosed. A method of making such cells is also disclosed. The method is used to make Bifidobacterium cells that lack certain functional antibiotic resistance genes, such as tetW, and are sensitive to antibiotics such as tetracycline.

Abstract: A novel gene of Bifidobacteria and the polypeptides encoded thereby. In particular, a gene belonging to the Serpin superfamily and its use in the production of bacterial Serpins is provided. Also provided are vectors, host cells, and methods for producing bacterial Serpin polynucleotides and/or polypeptides.

Abstract: A novel microorganism of the genus Bifidobacterium longum, in particular to its genomic and plasmid sequence and to a method of producing polypeptides of said Bifidobacterium, respectively. Also methods of detecting these nucleic acids or polypeptides, respectively. A data carrier is provided comprising nucleotide sequences and/or polypeptide sequences of NCC2705. In addition, the Bifidobacterium longum strain NCC2705 and also to food and pharmaceutical compositions containing said Bifidobacterium or active components thereof for the prevention and/or treatment of diarrhoea brought about by rotaviruses and pathogenic bacteria are provided.

Abstract: Recombinant strains of L. johnsonii which have capacities of surviving passage through the intestine, adhering to human intestinal cells and increasing phagocytosis of macrophages and which have a sequence of gene coding which is an L. johnsonii strain sequence of gene coding for D-lactate dehydrogenase modified so that the recombinant strain produces only L(+)-lactate.
