Evaluation of the Ribosomal Protein S1 Gene (rpsA) as a Novel Biomarker for Mycobacterium Species Identification

Figure 1

Phylogenetic tree based on rpsA gene sequences shows the relationship of the 47 type strains of mycobacteria and 1 outgroup strain. This tree was constructed by the neighbor-joining method. Topology was also evaluated by bootstrap analysis (MEGA program, 1000 repeats, with R. equi as the outgroup). The numerical values in the tree represent bootstrap results. The distance between two strains is the sum of the branch lengths between them.
