Hello! I know what they are testing for, i have it! It is a cousin to TB, and it is not contageous to anyone, not even other CFers. If it goes without treatment it spreads fast, i was on a triple combo of antibiotics for 2.5 years for it, now all is good. It landed me in hospital a lot until they finally tested for it, i don't recall the name of it, but yeah it seems to be gone now!
