Due to the strain-specific nature of phages, it is impossible to create a phage therapy product that eradicates all the strains of bacteria in one's environment - and Phage Cures, LLC cannot provide any assurance whatsoever that the phage therapy products it offers for sale will successfully cure any particular infection you may have contracted. Nevertheless, we can attest to the proven effectiveness of phage therapy in eliminating an array of potentially dangerous bacterial pathogens, including Methicillin-Resistant Staphylococcus aureus (MRSA) - and due to phage therapy's versatility as a treatment for infection or as preventative medicine, we certainly believe that you can become healthier by making phage therapy part of your medical arsenal.
Phage therapy preparations normally consist of a phage "cocktail" - or a mixture of multiple phages - which a) enables the phage therapy preparation to work against a broader spectrum of bacterial pathogens and b) reduces the ability of bacteria to develop resistance against phages. In the latter case, "'using multiple phages targeting the same [bacterial] pathogen in a cocktail provides a built-in contingency against the development of phage resistance in bacteria.'"1 In other words, as bacterial pathogens evolve to foil specific phage predators, other phages will still be available to kill that bacteria; leading to a more thorough eradication of that particular bacterial pathogen (and ensuring that no "strong" bacteria survive to develop a more generalized resistance to phages). Due the fact that individual bacterial pathogens might ultimately become resistant to all the phages contained in a particular phage cocktail, however, the necessity periodically arises to introduce new phages into the cocktail. This addition or substitution ensures that "when [bacterial] mutants emerge, new phages with full potency can replace those that no longer work."2
The phage therapy products which Phage Cures, LLC sells are regularly "updated" to ensure their continued effectiveness. Yet, because phages are "strain-specific," the possibility always exists that these products will not contain any phages that attack the specific strain of bacteria which you have encountered. Accordingly, it is important that you become familiar with the prophylactic - or preventative medicine - component of phage therapy.
