Fig 1. The viability of Mycobacterium tuberculosis H37Rv growing at either a fast growth rate or a slow growth rate in response to isoniazid exposure.
The viability of Mycobacterium tuberculosis H37Rv growing at either a fast growth rate (Panel A; stars: Culture INH23.1, circles: Culture INH23.2, & triangles: Culture INH23.3) or a slow growth rate (Panel B; stars: Culture INH69.1, triangles: Culture INH69.2, & circles: Culture INH69.3) for at least 7 MGT in response to isoniazid (0.5 mg L-1) added at 0h and continuously throughout culture. Each line represents viable count data from an individual chemostat culture. The dotted lines in each case are control cultures without isoniazid addition.
