Bayesian inference phylogenetic tree of the core region.

A phylogenetic tree was constructed based on the core region (418 nucleotides), corresponding to nucleotide numbering of 300–717 in the H77 genome, using the GTR+I+G model of evolution. Numbers on branches are posterior probabilities from the Bayesian inference analysis. Reference sequences are labeled to the right of each branch in the order of subtype hyphen GenBank accession number. Ethiopian sequences are shown in color (color corresponding to their geographic origin: Red = Addis Ababa; Blue = Adama; Green = Mekelle; Pink = Gondar; Light blue = Jimma), a potential recombinant MK32ETH highlighted in yellow.
