The prevalence of antibiotic resistance determined by molecular pathologic tests. The gray histogram indicates the percentage of antibiotic resistance in first-treated patients who were treated for the first time, and the black histogram indicates the percentage in re-treatment patients who failed in bismuth quadruple therapy. As demonstrated, the resistance rates to amoxicillin, clarithromycin, fluoroquinolone and tetracycline were 5.5%, 42.1%, 41.7% and 12.9%, in first-treated patients, whereas 11.7%, 79.7%, 70.7% and 30.0%, respectively, in re-treatment patients.
