Amoxicillin resistance with β‐lactamase production in Helicobacter pylori

17 Jul 2009

Abstract excerpt

BACKGROUND: Amoxicillin-resistant Helicobacter pylori with minimal inhibitory concentration (MIC) >or= 256 mg L(-1) was isolated from a gastritis patient. The aims were to investigate the mechanism of high-level amoxicillin resistance in H. pylori. MATERIALS AND METHODS: The beta-lactamase production was determined by means of nitrocefin sticks and the presence of gene encoding the beta-lactam antibiotic...
