Location-specific bacterial management

A method of reducing pathogenic bacteria within one or more than one animal being reared in an animal rearing facility comprising,

• a. identifying location-specific isolates of one or more than one pathogenic bacteria at or near the animal rearing facility;
• b. identifying one or more than one bacteriophage strain naturally present in the animal rearing facility or site, local area, region, or continent, of the animal rearing facility, the one or more than one bacteriophage strain exhibits antibacterial activity against the one or more pathogenic bacteria, to obtain a location-specific bacteriophage preparation, the location-specific bacteriophage preparation comprising the one or more than one bacteriophage strain, phage components obtained from the one or more than one bacteriophage strain, or a combination thereof, wherein the one or more than one bacteriophage strain naturally present in the animal rearing facility is selected from a bacteriophage collection comprising bacteriophages isolated from:
• i) one or more different animal rearing facilities located at the site, the local area, the region, the continent,
• ii) one or more different animal rearing facilities located at a different site, a different local area, a different region, a different continent,
• iii) a global phage collection, or
• iii) any combination of i), ii), and iii);
• c. inoculating the one or more than one animal with the location-specific bacteriophage preparation, thereby reducing the pathogenic bacteria within the one or more than one animal being reared in the animal rearing facility.
