Phage technology was recently successfully used to treat antibiotic resistant endocarditis affecting the heart valves. I don’t remember the exact refetence but there is a lot of work on this treatment option. Good luck.
P.S. did you mean tobramycin?
Probably tobramycin; the doctors called it “Toby” for short, so likely you are correct.
Over the next few days I am going to do a comprehensive search for doctors that are treating with Phage technology in her area; it is now accepted as a “compassionate therapy”, so Medicare shouldn’t fight her over coverage. She has secondary insurance as well.
God Bless you!
