Bacteriophages (phages) are eco-friendly, naturally occurring microorganisms that target harmful bacteria. Their safety and effectiveness have been studied for over a century, with phage therapy used to combat bacterial infections for more than 100 years. In the United States, phages have been cleared for specific uses in food production and agriculture, and they naturally exist on human skin, eyes, mucous membranes, and throughout the gut microbiome-further underscoring their strong safety profile.
Safety and specificity of Bacteriophages (phages)
As precise "bacterial killers," the safety and specificity of bacteriophages can be summarized as follows:
Exceptional Safety: Bacteriophages are capable of recognizing and infecting bacteria exclusively; they do not recognize-nor do they bind to-receptors found on animal, plant, or human cells. Consequently, they exert no toxic side effects on the human body and do not interfere with normal physiological functions.
Rigorous Specificity: The relationship between bacteriophages and bacteria is akin to that of a "key and lock." Typically, a given bacteriophage targets only specific bacterial species-or even specific bacterial strains.
Applications in Agriculture and Animal Husbandry
In the agricultural and livestock sectors, bacteriophages are primarily utilized as a substitute for-or as an adjunct to-antibiotics. Administered via methods such as feed supplementation or spraying, they are applied to the following animal groups:
Poultry: Primarily chickens (both broilers and layers), ducks, and geese; used for the prevention and control of intestinal diseases caused by pathogens such as Salmonella and E. coli.
Livestock: Including pigs, cattle, and sheep; frequently employed to prevent and treat diarrhea in piglets and mastitis in dairy cows, as well as to reduce the carriage of pathogenic bacteria in animals raised for meat production.
Aquatic Animals: Fish, shrimp, crabs, sea cucumbers, and similar species; primarily used to suppress pathogenic bacteria-such as Vibrio and Aeromonas species-present in both the water environment and within the organisms themselves, thereby reducing mortality rates.
Well Sunshine Group have phages that target the following bacteria:
Escherichia coli, Salmonella, Vibrio (V. parahaemolyticus, V. alginolyticus, etc.), Edwardsiella (E. tarda, E. ictaluri, etc.), Clostridium perfringens, Riemerella anatipestifer, Pseudomonas aeruginosa, Proteus, Klebsiella pneumoniae, Staphylococcus aureus, Campylobacter jejuni, Haemophilus parasuis, Streptococcus suis, etc.
