From: Evaluating the anti Mycobacterium tuberculosis activity of Alpinia galanga (L.) Willd. axenically under reducing oxygen conditions and in intracellular assays

7 R3 Resistant to HERZ S531L S315T1/T2 mixed Wild type
  1. Antimycobacterial activity of A.galanga under anaerobic conditions was tested using only H37Rv.
  2. H-isoniazid, E-Ethambutol, R-Rifampicin, Z-Pyrazinamide.
  3. S- Drug susceptible strain.
  4. R- Drug resistant strain.
  5. *Phenotypic drug resistance was ascertained using the BACTEC MGIT 960 system.
  6. ΨGenotypic drug resistance was ascertained using the GenoType MTBDRplus assay (Hain Lifescience, Germany). Mixed indicates heteroresistance (presence of wild type and mutant bands).
