Figure Lengend Snippet: Neighbor-joining phylogenetic tree based on whole-genome multiple alignment of 24 Mycobacterium abscessus group genomes. Genomes in were aligned by using Mugsy , core segments of the alignment were identified by using Phylomark , and resulting concatenated nucleotide sequences were used for construction of the midpoint-rooted neighbor-joining phylogenetic tree by using MEGA . Strains from an outbreak of M. abscessus subsp. massiliense infections at a cystic fibrosis center in Seattle, Washington, USA, are indicated in red; strains from an outbreak of M. abscessus subsp. massiliense infections at a cystic fibrosis center in Papworth, UK, are indicated in blue (cluster 1) and purple (cluster 2); strains from Brazil are indicated in magenta; and the M. abscessus subsp. massiliense type strain is indicated in green. Boostrap values obtained after 100 iterations were ≥97 for all nodes of the tree except 70 for the node separating strain M115 from the outbreak cluster and 40 and 41 for 2 nodes within the Papworth cluster 1 . SNPs, single-nucleotide polymorphisms.

Figure Lengend Snippet: Venn diagram of core single-nucleotide polymorphisms (SNPs) shared by outbreak localities. Core segments of the Mugsy alignment of the 20 Mycobacterium abscessus subsp. massiliense genomes were parsed for SNPs shared by different subsets of outbreak localities. Each field in the Venn diagram represents nucleotides that are identical among isolates of that field but different in other isolates represented on the diagram and non–outbreak-related M. abscessus subsp. massiliense strains 1S-151–0930, 5S-0817, M115, M139, M154, and the type strain CCUG 48898 T . Details on SNPs and genes they affect are shown in the .

Figure Lengend Snippet: Neighbor-joining phylogenetic tree based on 13-target multilocus sequences types from 20 Mycobacterium abscessus subsp. massiliense genomes. Electronic PCR was performed on the M. abscessus subsp. massiliense genomes listed in by using primer pairs for 13 housekeeping genes ( cya , gdhA , argH , glpK , gnd , murC , pgm , pknA , pta , pur , rpoB , hsp65 , and secA1 ), including new primers designed as part of this study. Nucleotide sequences from each gene were concatenated for each genome and aligned by using ClustalW , and the core alignment was used for construction of a midpoint-rooted neighbor-joining phylogenetic tree by using MEGA . Strains from an outbreak of M. abscessus subsp. massiliense infections at a cystic fibrosis center in Seattle, Washington, USA, are indicated in red; strains from an outbreak of M. abscessus subsp. massiliense infections at a cystic fibrosis center in Papworth, UK, are indicated in blue (cluster 1) and purple (cluster 2); strains from Brazil are indicated in magenta; and the M. abscessus subsp. massiliense type strain is indicated in green. The longer branch length for Papworth isolate 12c was caused by low-quality nucleotides (single-nucleotide polymorphisms [SNPs]) located at the edge of Velvet contigs.
