Representative gels of PCR amplified fragments. a 16S RNA fragment. Lanes: MW—molecular weight marker (bp), NC—negative control, PC—positive control (DNA from strain ATCC 43504), 4 to 7—clinical isolates UEGE-640, UEGE-697, UEGE-748, and UEGE-752. b cagL fragment amplified with the first set of primers (651 bp). Lanes: MW—molecular weight marker (bp), NC—negative control, PC—positive control (DNA from strain ATCC 43504), 4 to 7—clinical isolates UEGE-640, UEGE-696, UEGE-847, and UEGE-752. c cagL fragment amplified with the second set of primers (165 bp). Lanes: MW—molecular weight marker (bp), NC—negative control, PC—positive control (DNA from strain HP26695), 4 to 7—clinical isolates: UEGE-845, UEGE-652, UEGE-748, and UEGE-752. d cagL fragment amplified with the third set of primers (611 bp). Lanes: MW—molecular weight marker (bp), NC—negative control, PC—positive control (DNA from strain HP26695), 4 to 7—clinical isolates: HG-65, HG-155, HG-177, and UEGE-748
