Multiple amino acid substitutions in penicillin-binding protein-1A confer amoxicillin resistance in refractory Helicobacter pylori infection

6 Aug 2022

Abstract excerpt

BACKGROUND: Amoxicillin resistance in Helicobacter pylori is mainly associated with mutations in penicillin-binding protein-1A (PBP-1A). However, the specific amino acid substitutions in PBP-1A that confer amoxicillin resistance in H. pylori remain to be investigated. OBJECTIVE: This study aimed to investigate the molecular mechanism underlying amoxicillin resistance in patients with refractory H. pylori...
