Fig. 1From: Acetone leaf extracts of some South African trees with high activity against Escherichia coli also have good antimycobacterial activity and selectivity indexThe mean MIC values (mg/ml) of acetone leaf extracts of the different medicinal plants and the positive controls (Streptomycin and Rifampicin) against M. smegmatis, M. fortuitum and M. aurum. Legend: a, b and c = no statistical significant difference in the mean MIC values, p < 0.05.
