Schematic diagram of full-length, IncA/C, and blaCMY-2 plasmids. (A) The aadA region is absent from pAM04528. (B) The traD, traL, traE, and traK genes are absent from peH4H. (C) A 22-kbp region downstream from the blaCMY-2 region is absent from peH4H. (D) The kan region is present in peH4H between insB3 and insB4. (E) IS1294 is found only in pAR060302. (F) Only a single copy of blaCMY-2 is present in pAR060302. The portions of the sequence that are not highlighted are identical in these plasmids, except for minor differences noted in Table 2. Bars, 10,000 bp.
