FIG. 1 A minimum spanning tree based on 24-MIRU-VNTR genotyping of 338 Mycobacterium tuberculosis Beijing isolates. The circles represent different types classified by 24-MIRU-VNTR genotypes and were coloured according to the ST classification described in the text. The sizes of circles represent the number of isolates with a particular genotype.

FIG. 2 Scheme of the proposed evolution of Beijing lineages. The scheme is based on the deletion of genomic regions (RD, region of difference, shown in grey rectangles), the NTF region with IS6110 insertions, and types of sequence designations from the studies of Filliol et al. [5] and Iwamoto et al. [14].
