Provided herein are methods and compositions for killing a target bacterium. Also disclosed are engineered bacteriophages.

The present invention relates to Myoviridae bacteriophage Vib-PAP-4(Accession No. KCTC 13168BP), isolated from nature, which possesses ability to specifically kill Vibrio parahaemolyticus bacteria and has the genome represented by SEQ ID No: 1, and a method for preventing infection of Vibrio parahaemolyticus bacteria and treating infection of Vibrio parahaemolyticus baceteria, using a composition containing the bacteriophage as an effective ingredient.

The present invention relates to a Myoviridae bacteriophage Vib-PAP-7 (Accession number: KCTC 13247BP) isolated from nature, which has the ability to kill Vibrio parahaemolyticus and has the genome represented by SEQ ID NO: 1, and a method for preventing or treating a disease caused by Vibrio parahaemolyticus using a composition containing the Myoviridae bacteriophage Vib-PAP-7 as an active ingredient.

The present invention relates to a Myoviridae bacteriophage Esc-CHP-2 that is isolated from the nature and can kill specifically enteropathogenic E. coli strains, which has a genome represented by the nucleotide sequence of SEQ. ID. NO: 1 (Accession NO: KCTC 12661BP), and a method for preventing and treating the infections of enteropathogenic E. coli using the composition comprising said bacteriophage as an active ingredient.

The present invention relates to a Myoviridae bacteriophage Clo-PEP-1 that is isolated from the nature and can kill Clostridium perfringens cells specifically, which has the genome represented by nucleotide sequence of SEQ. ID. NO: 1 (Accession NO: KCTC 12664BP), and a method for preventing and treating the infections of Clostridium perfringens cells using the composition comprising said bacteriophage as an active ingredient.

The present invention relates to a Myoviridae bacteriophage Esc-COP-1 that is isolated from the nature and can kill specifically Shigatoxin-producing type F18 E. coli strains, which has a genome represented by the nucleotide sequence of SEQ. ID. NO: 1 (Accession NO: KCTC 12662BP), and a method for preventing and treating the infections of Shigatoxin-producing type F18 E. coli using the composition comprising said bacteriophage as an active ingredient.

Disclosed herein are methods for the production of mutant bacteriophages with altered host range. Additionally, disclosed herein are methods and systems for rapid detection of microorganisms such as Listeria spp. in a sample. A genetically modified bacteriophage is also disclosed which comprises an indicator gene in the late gene region. The specificity of the bacteriophage, such as Listeria-specific bacteriophage, allows detection of a specific microorganism, such as Listeria spp. and an indicator signal may be amplified to optimize assay sensitivity.

The present disclosure relates to bacteriophage and compositions capable of infecting and killing Pseudomonas, and use of the same for treating Pseudomonas, e.g. Pseudomonas aeruginosa, bacterial infections.

The present invention relates to a Myoviridae bacteriophage Esc-CHP-1 that is isolated from the nature and can kill specifically enterohemorrhagic E. coli strains, which has a genome represented by the nucleotide sequence of SEQ. ID. NO: 1 (Accession NO: KCTC 12660BP), and a method for preventing and treating the infections of enterohemorrhagic E. coli using the composition comprising said bacteriophage as an active ingredient.

The present invention relates to a Myoviridae bacteriophage Esc-COP-4 that is isolated from the nature and can kill specifically enteroinvasive E. coli strains, which has a genome represented by the nucleotide sequence of SEQ. ID. NO: 1 (Accession NO: KCTC 12663BP), and a method for preventing and treating the infections of enteroinvasive E. coli using the composition comprising said bacteriophage as an active ingredient.
