Figure 3From: Evolution of extensively drug-resistant Mycobacterium tuberculosisfrom a susceptible ancestor in a single patientGrowth efficiency in the presence of antibiotics of clinical isolates harboring different resistance mutations. Growth in antibiotics relative to untreated controls (from the left: INH, STR, EMB). See main text for details. Color shading indicates the specific resistance mutation present in each isolate. Isolate SF8 contains a mixture of two populations with two different embB mutations.Back to article page
