Helicobacter pylori amoxicillin heteroresistance due to point mutations in PBP-1A in isogenic isolates

13 Jan 2008

Abstract excerpt

OBJECTIVES: To investigate the Helicobacter pylori amoxicillin resistance rate, the occurrence of heteroresistance, and their related molecular mechanisms. METHODS: Eighty-seven H. pylori-positive patients were included: 45/87 with single biopsy and 42/87 with multiple biopsies. MICs were determined, and sequencing analysis of pbp1A gene and the variable regions of seven hop porins was performed in resistant and...
