Recombinantly-modified Cutibacterium acnes-specific bacteriophage, and recombinantly modified bacteriophage-derived endolysin enzyme are provided. Such compositions, alone or in combination with other antimicrobial agents or immunomodulators, may be used in pharmaceutical compositions, particularly pharmaceutical compositions to treat acne, promote wound healing, inhibit the growth of biofilms and to decrease the likelihood of, prevent or treat surgical related infections. The present invention is particularly directed to such formulations that are compounded for topical administration to a subject or used for application to medical devices. In particular, such pharmaceutical compositions may be compounded for topical administration to a subject, or compounded for application to a medical device.

The invention discloses a method to prepare proteoliposomes using glycerol or polyethylene glycols (PEG) in the rehydration step. The method eliminates the use of expensive surfactants and subsequent time-consuming removal of those surfactants during the preparation of proteoliposomes. The fusible proteoliposome reconstituted with phage portal proteins or other hydrophobic channel proteins are useful for nanopore sensing technology, including ultrafast DNA sequencing and biomedical diagnostic applications.

Provided is a novel bacteriophage CJ23 (KCCM11365P). In addition, the present invention relates to an antibacterial composition including the bacteriophage CJ23 (KCCM11365P) as an active ingredient. Further, provided is a method of preventing and/or treating infectious diseases by avian pathogenic Escherichia coli(APEC) in birds using the bacteriophage CJ23(KCCM11365P) or the antibacterial composition containing the bacteriophage CJ23(KCCM11365P) as an active ingredient.

The present invention is in the field of recombinant biotechnology, in particular in the field of protein expression. The invention generally relates to methods of increasing the expression level of a protein of interest of a bacterial host cell in a production process. The invention relates particularly to improving the capacity of a bacterial host cell to express a protein of interest by expressing a phage protein during the production process which inhibits growth of the bacterial host cell. Decoupling growth of the bacterial host cell of manufacturing of the protein of interest during the production process reduces (i) the metabolic burden, (ii) oxygen demand, (iii) metabolic heat development, and (iv) avoids stress response caused by heterologous protein expression and thereby increases the capacity of a host cell to produce the protein of interest. The present invention also relates to uses of the host cell for protein expression, cell culture technology, and more specifically to culturing host cells to produce a protein of interest.

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.

Provided herein are bacteriophages engineered to express an exopolysaccharide (EPS) depolymerase for treating bacterial infections. In some embodiments, the EPS depolymerase comprises alginate lyase. Also envisioned within the scope of the invention are compositions comprising one or more of the bacteriophages, methods for treating bacterial infections, and kits comprising the compositions described herein.

The present invention relates to novel bacteriophages specific to Klebsiella pneumoniae strains, and compositions comprising the same. Particularly, polypeptides and their coding nucleic acid molecule of the novel bacteriophages are provided. The invention also relates to applications of the novel bacteriophages and the polypeptides in the detection/treatment/prevention of infection caused by Klebsiella pneumoniae strains. Development of immunogen and vaccine on the basis of the polypeptides are also provided.

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

Methods to obtain expression systems and proteins in a high-throughput protocol by utilizing mixtures of cells cultured from those transformed with a desired nucleotide sequence permit rapid production of protein for use in arrays to assess activity. In one embodiment, the proteins (or peptides) in the array are assessed for their immunological activity with regard to an infectious agent.
