Phages are specific to a bacteria. Each type of bacteria needs a different phage. As far as I know, the only NTM that they have found a phage for is abscesses. They also have found phage for pseudomonas aeruginosa. I, too, hope we can all benefit from phage therapy one day, without accompanying antibiotics. UC San Diego was doing phage treatment a few years ago. Not sure if that program is still going on, but you can certainly read their website. https://idgph.ucsd.edu/research/center-innovative-phage-applications-and-therapeutics/index.html. In my opinion the pharmaceutical industry doesn’t want phages to be available. Here’s a fascinating BBC video. https://youtu.be/bmKMIP91lTE
