摘要:
The invention concerns a feed additive of antimicrobial properties, a concentrate, use of a feed additive to manufacture a concentrate as well as a method of production of the feed additive. A more detailed solution concerns a feed additive of antimicrobial properties restricting the activity of endogenous microflora of the gastrointestinal tract, in particular of Listeria, Salmonella and Clostridium. The action of supplements consists in the improvement of poultry performance (gains and feed utilisation) by limiting the activity of endogenous microflora, especially Listeria, Salmonella and Clostridium.
摘要:
The present invention relates to the fields of life sciences and food, feed or pharmaceutical industry. Specifically, the invention relates to novel peptides, pilus structures, polynucleotides as well as vectors, host cells, products and pharmaceutical compositions comprising the polynucleotides, peptides or pilus structures. The invention also relates to gene clusters and antibodies. Furthermore, the present invention relates to methods for producing the peptides or pilus structures or producing the products comprising the peptides or pilus structures. Furthermore, the present invention relates to treatments as well as uses and methods for screening bacterial strains, for reducing or inhibiting the adhesion of pathogenic bacteria, promoting the adhesion of bacterial cells to the mucus and for modifying immune response in a subject. Still, the present invention relates to methods for detecting probiotic bacterial strains or pathogen strains.

摘要:
Novel polynucleotides isolated from Lactobacillus rhamnosus , as well as probes and primers, genetic constructs comprising the polynucleotides, biological materials, including plants, microorganisms and multicellular organisms incorporating the polynucleotides, polypeptides expressed by the polynucleotides, and methods for using the polynucleotides and polypeptides are disclosed.
摘要:
Nucleotide sequences coding for a promoter activity-regulating polypeptide designated OrfY, isolated from Lactococcus lactis , and promoter activity-regulating active homologues and fragments hereof is used to indirectly regulating the expression of genes. The coding sequence is inserted into lactic acid bacterial cells or any other cells with the objective of either reducing or enhancing the expression level of the gene being under the control of the promoter sequence, the activity of which is regulated by the OrfY polypeptide or homologues or fragments hereof. Improved gene expression systems are provided based on this promoter activity-regulating polypeptide.
摘要:
Live vaccines and methods for preparing the vaccines useful in protecting a host from infection by a pathogenic microorganism are provided. Vaccines are prepared from live Lactobacillus cells which have been transformed using DNA technology to express heterologous antigens of pathogenic microorganisms or other suitable biological material. Genes encoding antigenic determinants pathogenic in the mammalian gastrointestinal tract are inserted into expression cassettes and fused with genes encoding an aggregation factor and/or a mucin binding factor. The inserted genes are shown to transform L. reuteri cells. The aggregation enhancing and mucin binding genes have been isolated and sequenced. The vaccine can be ingested orally in a pharmaceutical carrier or in milk products.
