Activity of Medicinal Plant Extracts on Multiplication of Mycobacterium tuberculosis under Reduced Oxygen Conditions Using Intracellular and Axenic Assays

Figure 2

Intracellular inhibition of growth of H37Rv. Extracts of 4 plants were tested on intracellular growth of H37Rv in A549 cells at 25 μg/mL with MOI of 1 : 1. The extracts showing greater than 60% inhibition of bacterial growth 10 days after infection were selected for testing under anaerobic conditions in an axenic setup.
