![Map of the 28-kb region deleted in Bordetella pertussis strains I979 and FR3749, compared with vaccine strain Tohama I. Vertical lines indicate the deletion boundaries, at a nucleotide G of the IS481 6-base insertion site motif. The deleted region is flanked by a single IS481 on each end in Tohama I and FR3749; I979 contains a second tandem IS481 downstream of the deletion. In Tohama I, IS1002 is located in the deletion region immediately upstream of IS481, and they share the 6-base motif.](/eid/images/15-1332-F2.jpg)
