and biopsy (eg histological examination, culture and rapid urease test) and by non-invasive …

Background: Three point mutations (A2143G, A2142G, and A2142C) have been involved in
Helicobacter pylori clarithromycin resistance. Objective: To compare the eradication rates …

The main cause of failure of Helicobacter pylori eradication therapy is resistance to
clarithromycin. The resistance is due to three point mutations in two positions on the 23S …
