  • Publication number: 20200317738
    Abstract: The invention describes peptide, and proteins and fusion proteins comprising the peptides, that are capable of increasing the proliferation of cells, especially epithelial cells in the mammalian gastrointestinal tract. The peptides comprise the hydrophilic domain of the TadE subunit of the Tad pilus of Bifidobacterium, especially the pilus encoded by the Tad2003 gene cluster identified in Bifidobacterium breve UCC2003, and functional fragments of the hydrophilic domain. The invention informs new treatments for diseases and conditions that involve attenuated epithelial cell proliferation and growth, such as inflammatory conditions of the gastrointestinal tract and trauma of the skin including burns and other wounds. The invention also informs treatments of newborn babies to promote proliferation and growth of gut epithelial tissue by administration of agents comprising the peptide of the invention in the form of infant formula.

  • Patent number: 10519516
    Abstract: The present invention relates to a kit suitable for detection of Streptococcus thermophilus infecting phages, said kit comprising: (a) a first primer pair suitable to generate an amplicon characteristic for a 987 phage; and (b) a second primer pair suitable to generate an amplicon characteristic for a 5093 phage. Further, the present invention relates to a method for detecting the presence of Streptococcus thermophilus infecting phages in a sample.

  • Patent number: 10519519
    Abstract: Bacteriophage Insensitive Mutants (BIMs) of three Streptococcus thermophilus parent strains were generated and characterized for phage sensitivity, sedimentation rate, cell chain length, phage adsorption and CRISPR loci alterations. Several BIMs showed an altered sedimentation phenotype as well as an increase cell chain length, reduced phage sensitivity, reduced phage adsorption and 100% identity in three CRISPR loci. The results show that the derived BIMs have become phage-resistant through a mechanism other than CRISPR.

  • Patent number: 10244771
    Abstract: The present invention provides a method for the construction of a bacteriophage-insensitive mutant of a Streptococcus thermophilus parent strain whereby the bacteriophage insensitivity is not based on the CRISPR resistance mechanism but based on another mechanism. The method provides a protocol by which this can be achieved by inactivating one or more of the CRISPR systems present in a given strain. The invention also provides the bacteriophage-insensitive mutants as well as their use in a process for making a dairy product.

  • Patent number: 10184127
    Abstract: The present invention concerns a method for genetically transforming a Bifidobacterium strain comprising a step of methylation of a shuttle vector in an E. coli or a Gram-positive bacterium strain by two type II DNA methyltransferases from a Bifidobacterium: a methyltransferase enzyme that methylates the adenine base at position 4 of the nucleotide sequence RTCAGG and a methyltransferase enzyme that methylates the cytosine base at position 4 of the nucleotide sequence GGWCC. The present invention also concerns genetic tools and culture media useful for carrying out said method.
