Comparison of survival of mice after infection with M. tuberculosis strains within 125 days p.i. in the similarly designed studies. The same strain H37Rv was used as reference. (a) ancient Beijing sublineage (this study). Strain 6691 belongs to 1071-32- cluster (RD181 deleted), strain 396 belongs to 14717-15-cluster (RD181 intact). (b) modern Beijing sublineage (adapted from Bespyatykh et al. [14]). B0/W148 strain is also named Russian epidemic or successful cluster. CladeA, CAO, NK strains belong to Central Asian Russian clade. The green colour is used to show that all clinical isolates in this panel belong to the modern sublineage of the Beijing genotype. Phylogenetic position of these clades and clusters is shown in Figure S1.
