Effect of Helicobacter pylori on basal pepsinogen secretion from dispersed human peptic cells according to the absence/presence of the cagA gene. Results are presented as mean (SEM) of 14 separate experiments. Basal secretion=5.2 (0.32)%. The H pylori strains used in these experiments correspond to strains HP33, HP52, HP59, HP66, HP61, HP62, HP63, and HP65.
