Fig 1.

Organization of the tet(O)-harboring region in C. coli 6067 and C. jejuni IA3902 and genomically equivalent regions in other Campylobacter genomes. Arrow orientations indicate the putative directions of transcription. ORFs flanking the tet(O) cassette and conserved (cons.) among the genomes are in black. ORFs composing the cassette are in gray, while the putative citrate transporter ORF harboring the tet(O) cassette is in white. ORFs unique to specific genomes are striped. P1, P2, P4, P5, P7, and P8 are primers, which are also listed in Table 2. hypoth., hypothetical.
