Schematic representations of the genomic islands interrupting comM and dusA in the A. baumannii clinical strains under study. (a) Tn6022 elements found interrupting the comM gene in the three strains under study (see Table 2 for details). The direct repeat generated at the site of integration is shown enlarged and underlined. In the Tn6022 element found in Ab242, an additional ISAba125 element was localized downstream of the uspA gene. The sites of hybridization of the pair of primers (see Table S1) employed to corroborate this insertion by PCR amplification analysis is shown. (b) Genomic island interrupting the dusA gene in the Ab244 strain (see Table 2 for details). Copper and arsenic ion-resistance clusters are underlined by green and orange bars, respectively. Genes encoding hypothetical phage proteins (grey arrows) are underlined by a grey bar. For comparisons, the intact dusA gene and its flanking genes found in the chromosomes of both Ab242 and Ab825 strains are shown below.
