Two CRISPRs detected in the five S. Typhimurium strains.

<p>(A) Genetic map of the two CRISPR/<i>cas</i> systems present in <i>Salmonella</i> Typhimurium UK-1. 17 <i>cas</i> genes were detected around the two CRISPRs. Three core <i>cas</i> genes are noted with red triangles. (B) Overview of the two CRISPR loci in the five <i>S.</i> Typhimurium strains. The repeats are shown as dark diamonds. Spacers are shown as colored rectangles. In each CRISPR, spacers with identical sequence in the studied genomes are shown in the same color. The white rectangles indicate the strain specific spacers.
