Mixed infections detected by IS6110 RFLP and spoligotyping. Spoligotypes and IS6110 RFLP patterns of the M. tuberculosis isolates that were identified as mixed infections on the basis of discordant genotyping results. The dendrogram (shown on the left) shows the similarity of the spoligotype patterns, as determined by using the Dice coefficient and unweighted-pair group method using average linkages for clustering. To the right of the IS6110 RFLP patterns, the interpreted genotype families are indicated, as determined by spoligotyping and IS6110 RFLP typing, respectively.
