from its two most related ancestors of Mycobacterium, M. leprae and M. tuberculosis. M. lepromatosis exemplifies a 9.1% deviance from M. leprae in nucleotide structure, evidence of a novel bacterium. A phylogenetic analysis of 20 genes and pseudogenes, isolated to 5 conserved protein genes, was used to construct phylogenetic trees displaying long terminal branches from the nodes, suggesting speciation occurred long ago.
