Schematic comparison of the trailer end of the arrays of spacers in <i>Acinetobacter baumannii</i> AYE and <i>A</i>. <i>baumannii</i> ab299505.

<p>The region carrying spacers Ab-1 to Ab-4 in <i>A</i>. <i>baumannii</i> AYE was missing in <i>A</i>. <i>baumannii</i> ab299505, most likely due to an internal deletion caused by a recombination event between the two direct repeats (highlighted by a black frame) surrounding the deleted region. This created a unique direct repeat (highlighted by a black frame and vertical lines) characterized by a novel mosaic sequence derived from the recombined direct repeats. Sequence of the direct repeats involved in the recombination was presented in adjacent black boxes.</p

Graphic representation of the arrays of spacers in the CRISPR-<i>cas</i> subtype I-Fb locus of <i>Acinetobacter baumannii</i>.

<p>The figure demonstrated the assortment of 74 <i>A</i>. <i>baumannii</i> isolates into 40 CRISPR sequence types (CST) based on the spacer content of their CRISPR arrays. Spacers were represented by red rectangles. Each unique spacer was assigned a number (1–876). Spacers were sequentially aligned in order to facilitate comparison among the CSTs.</p
