Genealogy of spoligotypes from pathotype A* strains. Postulated mutational events leading to the observed spoligotypes are indicated, starting from the ancestral spoligotype with all 23 spacers (Fig. 2) shown in grey on the top, with the colors indicating the number of events (from one to six events, colored in salmon, orange, yellow, green, blue and purple, respectively). Numbers of observed haplotypes are indicated in the circles. Characters indicate postulated intermediate haplotypes that were not observed among the 56 analysed strains
