Two example DRs found in M. tuberculosis strains. R3 and R4 are two DRs found in M. tuberculosis strains. 28 M. tuberculosis strains are divided into four groups, Group 1–4. Group 2 includes Strain 6 and 9, Group 3 includes Strain 21 and 28, Group 4 includes Strain 14 and Group 1 includes the remaining strains.
