San Fran, Miami, Denver, and a place in NY, are the experienced centers in the US, I'm not sure much real research is occurring for TB in the programs. But Denver is also the most competitive academic pulm fellowship out there.
There are programs that you will get lots of hands on with TB, my program runs the county health TB program so I'm very comfortable with everything up to MDR/XDR treatments, as thankfully it's still a rare condition.
