Abstract: A method for reducing the population of pathogenic bacteria in an animal being reared in an animal rearing facility is provided. The method involves using one or more than one naturally-occurring location-specific bacteriophages selected to be highly specific to the strains of the one or more than one pathogen present in the facility, a phage component derived from the one or more than one naturally-occurring location-specific bacteriophages, or a combination thereof, to produce a location-specific bacteriophage preparation. The preparation is administered to the animal, to reduce the one or more than one pathogenic bacteria. The method may also involve a step of identifying location-specific isolates of the one or more than one pathogenic bacteria at or near the animal rearing facility.

Abstract: Stabilized bacteriophage compositions, and methods for preparing stabilized bacteriophage compositions are provided. The method for producing an antibacterial composition involves adsorbing an aqueous solution of one or more bacteriophages, or one or more phage components, onto a matrix to produce a composition, and drying the composition to produce the antibacterial composition. An antibacterial composition comprising one or more strain of bacteriophage, or one or more phage component, adsorbed onto a matrix is also provided. The antibacterial composition, or the antibacterial composition embedded in a solid support, may be used within a cream, lotion or gel, be admixed with a pharmaceutical carrier and administered topically, orally, nasally, used as a powdered inhalant, or the antibacterial composition or encapsulated antibacterial composition, may be added to a feed for animal, aquatic or avian uses.

Abstract: An encapsulated bacteriophage formulation and a method for preparing encapsulated bacteriophage formulation is provided. The method for producing the encapsulated bacteriophage composition involves injection of a molten coating substance comprising stearic acid and palmitic acid present at a ratio of 50:50, into a granulator chamber containing immobilized bacteriophages. The immobilized bacteriophage are agitated by rotation of a base of the chamber and swept by a flow of air at a temperature of between 10° C. and 50° C.

Abstract: Bacteriophage compositions, and methods for preparing bacteriophage compositions are provided. The method for producing an antibacterial composition involves adsorbing an aqueous solution of one or more bacteriophages, or one or more phage components, onto a matrix to produce a composition, and drying the composition to produce the antibacterial composition. An antibacterial composition comprising one or more strain of bacteriophage, or one or more phage component, adsorbed onto a matrix is also provided. The antibacterial composition may also be encapsulated. The antibacterial composition, or the encapsulated antibacterial composition, may be used within a cream, lotion or gel, be admixed with a pharmaceutical carrier and administered topically, orally, nasally, used as a powdered inhalant, or the antibacterial composition or encapsulated antibacterial composition, may be added to a feed for animal, aquatic or avian uses.

Abstract: The present invention is directed to a process for reducing a population of one, or more than one target pathogen present in animal waste, including livestock manure , comprising administering one, or more than one protected bacteriophage strain to livestock. The one, or more than one bateriophage strain is capable of adsorbing to and killing the target pathogen, is released in vivo, and acts to clear the one or more than one pathogen from livestock gut and waste. The one, or more than one bacteriophage it further reduces the population of the one or more than one target pathogen in the waste or manure. The present invention also relates to a process for reducing a population of one, or more than one target pathogen present in liquid manure comprising treating the animal waste such as liquid manure with one, or more than one protected bateriophage strain, or phage components, or a combination thereof.

Abstract: The present invention is directed to method for reducing a population of a target pathogen in an animal or within a feedlot. The method involves administering one or more than one controlled release bacteriophage strain or phage component, or both, to the animal, so that the one, or more than one bacteriophage strain is released in vivo and adsorbs to the one or more than one target pathogen, thereby reducing the one, or more than one pathogen from the animal. The controlled release bacteriophage strain or phage component may be administered as a treatment dose prior to further processing of the animal, a treatment dose followed by a maintenance dose, or a maintenance dose, to manage feedlot target pathogens.

Abstract: The present invention is concerned with genetically labeled bacteriophages, and with methods for preparing and using the same. Genetically labeled phages may easily be distinguished from non-labeled phages. The present invention also relates to methods for selecting therapeutic bacteriophages lysing pathogenic bacteria without cross-reacting with non-pathogenic bacteria. This method permits the selection of phages which are highly specific to given pathogenic bacteria. The present invention is also concerned with methods for evaluating bacteriophage susceptibility to external genetic modifications in order to provide bacteriophages that are safe and highly specific for use in the prevention, treatment and/or control of bacterial infections or contamination in plants, animals, and humans, as well as environmental cleanup and sanitation.
