Table 1 Minimum inhibitory concentration and minimum bactericidal concentration values of the plant solvent partitions against Mycobacterium tuberculosis H37Rv

From: Antituberculosis activity, phytochemical identification of Costus speciosus (J. Koenig) Sm., Cymbopogon citratus (DC. Ex Nees) Stapf., and Tabernaemontana coronaria (L.) Willd. and their effects on the growth kinetics and cellular integrity of Mycobacterium tuberculosis H37Rv

  1. “NI”: not showing inhibition even at the highest test concentration of 1600 μg/mL. “NC”: not showing cidal effect even at the highest test concentration of 1600 μg/mL. “ND”: MBC not determined. All positive control wells showed bacterial growth. Negative growth control drug, isoniazid exhibited consistent MIC and MBC values of 0.078 μg/mL
