Neighbor-joining tree based on the MIRU-VNTR and spoligotyping data for 43 clustered isolates (PDF). From left to right: i) Neighbor-joining tree based on the 24-locus MIRU-VNTR and spoligotyping data for the 43 isolates grouped in 19 clusters (built using the MIRU-VNTRplus analysis tool; ii) Number of repetitions of each VNTR according to the nomenclature by Supply et al. (2006) [18]; and iii) 43-spacer spoligotypes: black spots represent the presence and white spot represent the absence of 1–43 spacers (according to the numbering by Van Embden et al. 2000) [23]. Yellow squares, Beijing clusters; orange squares, EAI clusters; dark pink, T clusters
