  1. S streptomycin, H isoniazid, R rifampin, E ethambutol, MDR-TB multidrug resistant tuberculosis, pre-XDR pre-extensively drug resistant tuberculosis
  2. aPre-XDR TB is resistance to either a second-line injectable (kanamycin, capreomycin) or a fluoroquinolone (ofloxacin), but not both
  3. bone patient had resistance to both capreomycin and kanamycin, but not ofloxacin
