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

Figure 3

Activity of plant extracts under reducing oxygen concentration against H37Rv. The 5 intracellularly active plant extracts were tested on H37Rv under reducing oxygen concentration. Viable M.tb acted as the positive control whereas rifampicin was used as the experimental control. P. nigrum acetone extracts showed inhibition of bacterial growth under all 3 conditions. The results are represented as mean ± SD of three experiments.
