IS6110-based phylogenetic tree from the Azerbaijan data in Pfyffer, et. al. . IS6110-based phylogenetic tree for data set in . Each tip or leaf of the tree represents an isolate typed with both IS6110 and spoligotyping. The leaves are labelled with shared types (STs) from SpolDB4. Those spoligotype patterns not appearing in SpolDB4 (orphans) are labelled as Or1 and Or2. Forty-six isolates consisting of 25 different IS6110 profiles are all represented by ST 1.
