Figure 1. Distribution of MIC (minimum inhibitory concentrations) values of isolated H. pylori in response to (A) amoxicillin, (B) clarithromycin, (C) metronidazole, and (D) levofloxacin.

Figure 1

H. pylori was isolated from patients enrolled for first-line therapies (naïve group) and, among rescue groups, patients who had previously received amoxicillin, clarithromycin, metronidazole or levofloxacin only once on anti-H. pylori therapies (antibiotic once recipient group). The breakpoint for resistance to each antibiotic was indicated by the vertical dash line.
