^aIncA/C plasmid core regions are based upon the assay by Welch et al. (39), in which core regions are numbered in order 1 to 12 around the plus strand of the IncA/C plasmid sequence. Core regions are scored as present if the probes (highlighted in yellow in Fig. 1) were detected by microarray analysis of the isolate. The core region number is shown if the probe was detected by microarray analysis of the isolate. −, absent by microarray analysis.

^bn is the number of isolates with the same pattern.

^cIsolates 544, 517, 910, 897, 515, and 911 show the same pattern.

^dIsolates 604, 894, 518, 918, 915, and 573 show the same pattern.

^eIsolates 728 and 886 show the same pattern.

^fIsolates 552, 528, 674, 617, 587, 562, 845, 745, 514, 631, 930, 584, 519, 856, 633, 851, 752, 625, 550, 521, 621, 667, 600, 824, 934, 822, 563, 889, 812, 732, 733, 553, 548, 890, 888, 858, 589, 792, 784, 612, and 649 are positive for all 12 core regions. These regions are identified with the full hybridization data in Fig. 1.
