Abstract excerpt

Clinical outcomes of Helicobacter pylori infection range from chronic gastritis to peptic ulcer disease and gastric cancer. Yet data on strain diversity and clinical outcomes remain scarce in North Africa. This study aimed to characterise enzymatic and genetic variation among H. pylori isolates from symptomatic patients in western Algeria. From 428 patients, 72 H. pylori strains were isolated and purified; for...
