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 cocktails thereof, 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.

The present disclosure relates to chimeric bacteriophage lysins useful for the identification and/or reduction of staphylococcal populations. For example, a chimeric bacteriophage lysin was engineered and shown to effectively kill all strains of staphylococci tested including antibiotic resistant methicillin-resistant S. aureus (MRSA) and vancomycin intermediate S. aureus (VISA).

Compositions containing at least one siloxane and at least one active microbiological ingredient are useful for the treatment of plants, of seeds or of soils, as biostimulant or as probiotic food supplement or animal feed additive, or as probiotic medicament. In addition, the siloxane improves the storage stability of an active microbiological ingredient.
