FIG. 2.

Representative GenoType HelicoDR DNA strip results obtained with H. pylori strains and biopsy specimens showing (i) rrl alleles that are wild type (lanes 1 to 11) or mutated (12 to 15), (ii) gyrA alleles that are wild type (lanes 1, 3 to 11, and 15) or mutated (a mutation at codon 87 in lane 12 and no hybridization with probes of codon 87 in lane 2), and (iii) heterogeneity of the H. pylori population (lanes 7, 11, 12, and 15). NC, negative control; CC, conjugate control; AC, amplification control.
