Figure 2. Independent growth curves of drug susceptible and drug resistant strains.

The growth curves measured by plating for CFU of the drug resistant and susceptible strains in 7H9 broth over a period of 14 days have been plotted against time. The data is represented as mean ± SD of 3 independent experiments. (Figure 1A ) represents growth curves of drug susceptible and resistant strains of CAS lineage in single culture. (Figure 1B ) represents growth curves of drug susceptible and resistant strains of Beijing lineage in single culture. (Figure 1C ) represents growth curves of drug susceptible and resistant strains of MANU lineage in single culture. (Figure 1D ) represents growth curve of H37Rv in single culture.
