Disc diffusion measurements for ethambutol and selected derivatives in Middlebrook agar media against M. smegmatis. Derivatives were serially diluted from 25 μg/mL to 0.781 μg/mL, while ethambutol was diluted from 0.391 μg/mL to 0.0244 μg/mL. Inhibition was measured after two days of growth at 37°C.
