The whole process required for phage therapy: phage discovery; phage banking (that has to be implemented and maintained) with various phages targeting different bacteria; relevant clinical indication; phage therapy using a fixed cocktail, with a certain likelihood that some of the phages will not be not active; phage selection based on the phagogram (currently performed in France), with cocktail preparation and administration in hospital (green option); phage selection based on the phagogram, with phage training on the patient’s strain, which is not currently performed and is more time consuming than the previous options.
