FIG 1.
Genetic context of blaOXA-58 in A. seifertii isolate Ac-12.1. Genes are shown as labeled arrows; inverted repeats (IRs) of ISAba3 and ISAba825 are shown as flags (gray flags, ISAba3; black flags, ISAba825). The presence of a left IR (IRL) of ISAba3 upstream of blaOXA-58 suggests that insertion of ISAba825 occurred after transposon formation (ΔISAba3–blaOXA-58–ΔISAba3). Integral ISAba3 sequences are represented below the genetic context, and regions with similarity to ΔISAba3 are highlighted in light gray. The nucleotide sequence of the promoter region is boxed. The double bars in the127-bp nucleotide sequence represent the nucleotides omitted. Uppercase letters represent the start codons of ISAba825 and blaOXA-58.
