Figure 1: Representation of our 469-strain dataset [detailed in Table 1], classified according to resistance/susceptibility to rifampicin, presence/absence of mutations in rpoB, and presence/absence of mutations in rpoC or rpoA. The number in brackets indicates the number of strains with certain characteristics (i.e., there are 9 rifampicin-resistant strains that have a mutation in rpoC/rpoA but do not harbor mutations in rpoB)
