Structures of three different Acinetobacter baumannii resistance islands: Tn6167 (A), AbaR25 (B), and ΔAbaR25 (C) (GenBank accession numbers JN968483, JX481978, and JX481979, respectively). The genes and open reading frames (orf) are shown by labeled arrows, with the arrowhead indicating the direction of transcription. The mobile elements ISAba17, ISAba1, and CR2 are shown as labeled open boxes. Inverted repeats are shown as vertical bars. The vertical dashed arrow in panel A defines the transposition site of the second copy of Tn6022a in AbaR25. The vertical dashed arrows in panel B define the deletion in ΔAbaR25. The genes and genetic structures are drawn to scale.
