Abstract: A composition comprises bacteriophage covalently attached to an edible particle and is for use in treating bacterial infection in fish or crustaceans. Infections in fish or crustaceans caused by Vibrio, Aeromonas, Yersinia, Moritella, Rickettsia, Piscirickettsia, Lactococcus, Pseudomonas, Flavobacterium or Photobacterium bacteria species can be treated. Bacteria infected with a lysogenic bacteriophage are used for treating disease of fish or crustaceans caused by similar infections by bacteria carrying lysogenic bacteriophage that express a toxin gene.
Abstract: An intracellular bacterial infection in a plant or animal is treated by administration to a plant cell or animal cell of a particle to which an infectious bacteriophage is covalently attached, wherein the particle is internalized by the cell. Particles with phage attached and compositions comprising the particles are provided. A formulation, for treatment of a bacterial infection, comprises bacteriophage, liquid carrier and adhesive, which dries so that the adhesive adheres the bacteriophage to a surface, one such formulation comprising liquid carrier: 85%-99.98% by weight; bacteriophage: 0.01%-5% by weight; and adhesive: 0.01%-10% by weight.
Abstract: A method of binding bacteriophage to particles. The method comprising the steps of exposing the particles to an electrical discharge and then mixing the activated particles with the bacteriophage. The bacteriophage are then bound to the particles.
