Evolutionary history of Stenotrophomonas strains belonging to unknown species based on concatenated alleles of the MLST scheme using 16S rRNA sequences was inferred using the Neighbor-Joining method. The optimal tree with the sum of branch length = 0.18050158 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1050 replicates) are shown next to the branches. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The analysis involved 57 nucleotide sequences. There were a total of 1392 positions in the final dataset
