Schematic representation of bla NDM-associated genetic structures identified among Gram-negative clinical isolates. (a) Structure found in A. baumannii, where the bla NDM gene is part of the composite transposon Tn125. (b) Structures found in Enterobacteriaceae and P. aeruginosa where ISAba125 is presented as full or truncated element with ble MBL gene (bleomycin resistance encoding gene) also being present as full or truncated gene. Genes and their corresponding transcription orientations are represented by horizontal arrows. oriIS of ISCR21 is indicated by a circle. The bla NDM promoter is indicated (P). IS, insertion sequence; gene names are abbreviated according to their corresponding proteins: ble MBL, bleomycin resistance gene; Δiso for truncated phosphoribosylanthranilate isomerase; Δpac for truncated phospholipid acetyltransferase.
