This sounded interesting and so i read-up a little on "Phage Therapy". From what i could gather, it didn't take off in the West because of its narrow applicability and hence consequent economics weren't profitable. What is its current status today? Do you have some detailed article, study, research etc. that you could point us to? Love to hear more about it.
