Genome sequence-based phylogeny.

<p>The FastTree output is shown with local bootstrap support on respective nodes. CRISPR2 array type and ST are indicated. Unknown STs are shown with “?”. CRISPR2 arrays are organized from terminal spacer to leader spacer. Spacers in red are strain-specific. Spacers that have numbers in parentheses next to them indicate Single Nucleotide Variants (SNVs). For example, a spacer labeled 161 (12) indicates that spacer 161 is a SNV of spacer 12.
