The present invention concerns a production bacterial cell for producing phage particles or phage-derived delivery vehicles, said production bacterial cell stably comprising at least one phage structural gene(s) and at least one phage DNA packaging gene(s), said phage structural gene(s) and phage DNA packaging gene(s) being derived from a first type of bacteriophage, wherein the expression of at least one of said phage structural gene(s) and/or at least one of said phage DNA packaging gene(s) in said production bacterial cell is controlled by at least one induction mechanism, and wherein said production bacterial cell is from a bacterial species or strain different from the bacterial species or strain from which said first type of bacteriophage comes and/or that said first type of bacteriophage targets.

The invention is directed to antibacterial compositions comprising bacteria modified to comprise phasmids engineered to deliver of CRISPR RNAs and methods for their use.

A factor that is caused by a nucleic acid and influences the kinetics of an extracellular vesicle is screened. A library of barcoded extracellular vesicles is provided.

The invention relates to anti-CRISPR genes and anti-CRISPR proteins, and their uses in various biotechnology applications.

The present invention concerns a production bacterial cell for producing lytic phage particles or lytic phage-derived delivery vehicles, said production bacterial cell stably comprising at least one phage structural genes and at least one phage DNA packaging genes, said phage structural gene(s) and phage DNA packaging gene(s) being derived from a lytic bacteriophage, wherein the expression of at least one of said phage structural genes and/or at least one of said phage DNA packaging gene(s) in said production bacterial cell is controlled by an induction mechanism.

The present disclosure provides a chimeric receptor binding protein (RBP) resistant to proteolytic digestion wherein said RBP comprises a portion of a receptor binding protein derived from a bacteriophage fused through a designed linker region consisting of 1 to 70 amino acids, to a portion of a receptor binding protein derived from a different bacteriophage, wherein said linker region is designed to be resistant to proteolytic digestion.

The present invention relates to an antibacterial protein EFAL-2 derived from bacteriophage Ent-FAP-4 (Accession number: KCTC 12854BP), which has the ability to kill Enterococcus faecium and an amino acid sequence represented by SEQ ID NO: 2, a pharmaceutical composition containing the same as an active ingredient, and a method for preventing or treating diseases caused by Enterococcus faecium using the pharmaceutical composition.

The invention relates to C. acnes strains carrying DNA vectors for the production of recombinant C. acnes phages. The invention encompasses a C. acnes producer cell carrying DNA vectors, with a template for recombination with C. acnes phage genome leading to the insertion of a gene of interest, for the production of recombinant phages that can lead to the transgene expression into C. acnes infected by the recombinant phage. The invention encompasses, C. acnes strains containing these vectors, C. acnes recombinant phages and methods of using these recombinant phages.

Cells, compositions, and methods for producing and transplanting cells which exhibit reduced antigen presentation by the major histocompatibility complex type I (MHC-I) by decreasing or eliminating activity of a tapasin protein or homolog thereof are provided.

The present disclosure relates generally to bacterial delivery vehicles for use in efficient transfer of a desired payload into a target bacterial cell. More specifically, the present disclosure relates to bacterial delivery vehicles with desired host ranges based on the presence of a chimeric receptor binding protein (RBP) composed of a fusion between the N-terminal region of a RBP derived from a lambda-like bacteriophage and the C-terminal region of a different RBP.
