The invention also relates to compositions, bacterial diversity sets, and phage libraries prepared according to the methods of the instant invention.

The present invention relates to a method for preparing a bactericidal phage vector, (pharmaceutical) compositions comprising such phage vectors, also for use in treating diseases, particularly those caused by (antimicrobial resistance) bacterial cells.

A composition or matrix comprising a bacteriophage and nanofibrillar cellulose or a derivative thereof in a wet or dry state is disclosed.

A lyophilized test kit for determination of biological antimicrobial effectiveness of a phage lysate on the basis of a microtitration plate wherein individual wells of one series contain at least 50 μl of a lysate of one of the following phages or their combination: MB 401, MB 402, MB 403, MB SA2, MB SA3, MB SA5, namely in the ten-fold dilution at the concentrations of 1×10.sup.9-1×10.sup.2.

The subject matter of the instant invention relates to methods of compounding compositions comprising bacteriophage effective for treating bacterial infections, including but not limited to, multidrug resistant bacterial infections. The invention also relates to compositions, bacterial diversity sets, and phage libraries prepared according to the methods of the instant invention.

A method of treating, reducing or preventing bacterial infection in a wound, the method comprising: applying a film on the wound, the film including a biodegradable polymer with bacteriophages dispersed therein, wherein the polymer is a poly (ester amide urea).

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

The present invention is directed to the field of phage therapy for the treatment and control of bacterial infections, in particular respiratory bacterial infections such as bacterial pneumonia. More specifically, the present invention is directed to novel bacteriophage strains, and products and cocktails thereof, including F99/10, F110/10, F27/12, Psa_F83/13, Psa_F95/13, F391/08, Kle_F92/15, Kle_F105/15, Kle_F134/15, Kle_F141/15, as well as variants thereof; and methods of using same in the treatment and prevention of bacterial infections, including respiratory infections caused by, e.g., Pseudomonas aeruginosa and/or Klebsiella pneumoniae. The cocktails are used as pharmaceutical compositions either alone or in further combination with other therapies, e.g., antibiotics or other standard and non-standard therapies for respiratory infections.

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 invention describes a genetically modified Staphylococcus aureus bacteriophage VDX-10 comprising the DNA of the bacteriophage VDX-10 being altered by inserting a gene sequence that increases the ability of the bacteriophage to replicate faster as compared to unmodified VDX-10 bacteriophage; a method of producing the genetically modified Staphylococcus aureus bacteriophage VDX-10; and a method of treating infection in a patient by administering an amount of the genetically modified Staphylococcus aureus bacteriophage effective to eliminating the Staphylococcus bacteria cells, where the infection can be Ventilator-Associated Pneumonia (VAP) or bacteremia as incited by methicillin-resistant Staphylococcal aureus (MRSA) or methicillin-sensitive Staphylococcal aureus (MSSA).
