A preliminary phylogenetic tree obtained by the neighbor-joining algorithm on the basis of the 1-Jaccard index (Sj=a/a+c, where a is the number of simultaneously positive characters and c is the number of discrepancies), which is not exhaustive for all existing phylogenetic links. A total of 70 shared spoligotypes were analyzed (69 types shown in Figure 2 and Mycobacterium bovis BCG).
