  • Publication number: 20200121768
    Abstract: The invention relates to the improvement of endonuclease-based antimicrobials by blocking DNA repair of double-strand break(s) (DSB(s)) in prokaryotic cells. In this respect, the invention especially concerns a method involving blocking DNA repair after a nucleic acid has been submitted to DSB, in particular by a Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) associated programmable double-strand endonuclease. The invention particularly relates to the use of an exogenous molecule that inhibits DNA repair, preferably a protein that binds to the ends of the double-stranded break to block DSB repair. The invention also relates to vectors, particularly phagemids and plasmids, comprising nucleic acids encoding nucleases and Gam proteins, and a pharmaceutical composition and a product containing these vectors and their application.

  • Publication number: 20190367867
    Abstract: The present invention relates to an in vitro method of culturing a segmented filamentous bacterium strain, comprising co-culturing said segmented filamentous bacterium strain with a eukaryotic host cell, wherein the culture is performed at an O2 level inferior to 5% in a rich tissue culture liquid medium containing bacterial medium components including iron. The present invention also relates to methods for genetically modifying a segmented filamentous bacterium strain comprising a step a culturing the strain in vitro.

  • Publication number: 20190330606
    Abstract: Provided are Cas9 enzymes that have mutations that enhance their properties, relative to un-mutated Cas9. The altered Cas9 enzymes exhibit i) an increased rate of spacer acquisition, or ii) increased cleavage efficiency of targets with NAG PAMs, or a combination of i) and ii). The altered Cas9 enzymes comprise an amino acid substitution of 1473 and K500 in a Streptococcus pyogenes or similar Cas9 enzyme. Also provided are polynucleotides, including expression vectors that encode the Cas9 enzymes, cells that contain the polynucleotides, and methods of making and using such cells. The disclosure includes tagging, or labelling bacteria, and for enhancing phage acquired immunity in bacteria, such as those used in industrial processes, including the food and beverage industry, such as the dairy industry. The food products are also included.
