Core Tip

Core tip: Different antibiotic susceptibility between antrum and corpus biopsies of the stomach represents a phenomenon and a possible explanation for treatment failure. Resistant Helicobacter pylori (H. pylori) strains, as a possible reason for treatment failure may be missed in a reasonable number if just one biopsy from one anatomic site of the stomach is taken for H. pylori susceptibility testing.
