Isoniazid/pyrazinamide/rifampin (INH).
All of the above would suggest more than mere exposure. It would suggest active disease. The hospitalization for "antibiotic resistant pneumonia" in December 2006 plus the probability of active tuberculosis (TB) suggests that you may have an

You should seek clarification of the TB and the appropriateness of one drug therapy and further assessment of your immune status.
