Analysis of genetic variation within fur in vivo. The frequency of the FurR88H variant was examined among (A) 224 in vivo-adapted Helicobacter pylori strains isolated from gerbils maintained on iron-replete or iron-depleted diets and (B) 339 clinical H. pylori strains isolated from three independent and well-defined patient cohorts within Colombia and the USA.31–33Fischer’s exact test was used to determine statistical significance. **p<0.005 and ****p<0.0001. DYS, dysplasia; IM, intestinal metaplasia; MAG, multifocal atrophic gastritis; NAG, non-atrophic gastritis alone.
