The urease activity of Campylobacter pylori was measured over a range of pH values. In a citrate‐Hepes system, two peaks of activity were seen, at pH 5 and at pH 8. The former activity was inhibited by phosphate. Gastric campylobacter‐like organisms isolated from the stomachs of several mammals resembled C. pylori in possessing two urease activities with different pH optima.
