From: Key lime (Citrus aurantifolia) inhibits the growth of triple drug resistant Helicobacter pylori
a Effect of C. aurantifolia extract on growth of standard H. pylori strain ATCC 43526 and triple drug resistant (TDR) H. pylori strain. The number of visible colonies of H. pylori strain ATCC 43526 or TDR H. pylori was decreased in the presence of C. aurantifolia extract compared to that in the control without the presence of C. aurantifolia extract. b Urease activity test of standard H. pylori strain ATCC 43526 and triple drug resistant (TDR) H. pylori strain. We determined inhibitory effects of C. aurantifolia extract at dilution of 1:1 to 1:64 on urease activity of H. pylori strain ATCC 43526 and at dilution of 1:1 to 1:128 on urease activity of TDR H. pylori. c Dose-dependent inhibitory effect of C. aurantifolia extract on urease activities of H. pylori strain ATCC 43526 and triple drug resistant H. pylori strain. An increasing concentration of C. aurantifolia extract showed higher attenuation of urease activity (P < 0.001)
