FIG. 4.

Antibiotic resistance genes adjacent to CRs. The ends of the CRs associated with orf513 (CR1), orfA (CR2), and orf2 (CR3) are shaded boxes; and the unique regions are open boxes, with antibiotic resistance genes indicated by horizontal arrows. For unique regions adjacent to CR1, a closed end indicates the end of the unique region; and the adjacent number is the position of the first base of 3′-CS2 in the standard 3′-CS, or the −45 indicates 45 bp of a 59-be preceding bp 1 of the standard 3′-CS. In one case IRi marks this boundary. The sequences used here are from the GenBank accession numbers listed in Fig. 1 plus the following: ampC/R, GenBank accession no. AJ237702; blaCMY-9, AB061794; blaCTX-M-2, AJ311891; blaCTX-M-9, AF174129; dfrA19, AJ310778; qnr, AY070235; sul2, D37825; dfrA9, X57730; flo, AF231986; tetR/A (31), AJ250203; dfrA18, AY034138; ereB, X03988; tetR/A(G), AF261825.
