The present invention relates to bacteriophage therapy. More particularly, the present invention relates to novel bacteriophages having a high specificity against Pseudomonas aeruginosa strains, their manufacture, components thereof, compositions comprising the same and the uses thereof in phage therapy.

Methods and compositions are provided for preventing or reducing symptoms or disease associated with Xylella fastidiosa or Xanthomonas axonopodis in a plant. The invention provides novel bacteriophages virulent to Xylella fastidiosa or Xanthomonas axonopodis, including XfaMija and XfaMijo, and further provides methods for treating or preventing Pierce's Disease or Citrus Canker in plants.

The present disclosure relates to bacteriophage ΦCJ28 (KCCM11466P) and a composition containing the same as an active ingredient. Further, the present disclosure relates to a method for preventing and/or treating infective diseases caused by enterotoxic Escherichia coli (ETEC) of animals excluding humans by using the composition. A bacteriophage ΦCJ28 (KCCM11466P) has a specific ability to kill enterotoxigenic Escherichia coli.

The invention relates to the production of phage and non-replicative transduction particles using DNAs (eg, plasmids and helper phage, mobile genetic elements (MGEs) or plasmids with chromosomally integrated helper phage genes), as well as the phage, helper phage, kits, compositions and methods involving these. The non-replicative transduction particles can be used to deliver antibacterial agents comprising a guided nuclease system.

Methods and compositions are provided for preventing or reducing symptoms or disease associated with Xylella fastidiosa or Xanthomonas axonopodis in a plant. The invention provides novel bacteriophages virulent to Xylella fastidiosa or Xanthomonas axonopodis, including XfaMija and XfaMijo, and further provides methods for treating or preventing Pierce's Disease or Citrus Canker in plants.

Provided are a bacteriophage KFS-ST3 having specific killing ability for Salmonella typhimurium and its derived biofilm, and a pharmaceutical composition for preventing or treating infectious diseases caused by Salmonella, including the bacteriophage. The bacteriophage KFS-ST3 of the present disclosure has specific killing ability for Salmonella, but does not kill beneficial bacteria and has excellent acid resistance and heat resistance, and thus may be not only used for the prevention or treatment of infectious diseases caused by Salmonella typhimurium and its derived biofilm, but also widely used in antibiotic compositions, feed additive compositions, disinfectants, or cleaning agents.

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

A process for the preparation of unilamellar vesicles, wherein a unilamellar vesicle comprises an amphiphilic membrane enclosing an aqueous core; and compositions comprising unilamellar vesicles.

The process comprises providing a primary emulsion comprising an amphiphilic membrane forming component, a first aqueous phase W1 and a first oil phase O1. The first aqueous phase W1 is dispersed as droplets in the oil phase O1 such that the primary emulsion is a water-in-oil emulsion. The primary emulsion comprises droplets having a mean diameter of less than 1000 nm.

The process comprises combining the primary emulsion with a second aqueous phase W2 to produce a secondary emulsion that is a water-in-oil-in-water emulsion; dewetting to yield unilamellar vesicles in the secondary emulsion; and isolating the unilamellar vesicles.

The present invention relates to a Myoviridae bacteriophage ESC-COP-7 (accession number KCTC 13130BP) isolated from nature, and a method for preventing and treating infections from pathogenic Escherichia coli by means of a composition containing the Myoviridae bacteriophage ESC-COP-7 as an active ingredient, the Myoviridae bacteriophage ESC-COP-7 being characterized by having the capability to specifically kill Escherichia coli, and genome expressed by the SEQ ID 1.

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.
