Aims: To test whether a hypoacidic environment may potentially "stress" Helicobacter pylori DNA, encouraging the emergence of strain variation. Methods: This hypothesis was tested by inducing prolonged hypoacidity with omeprazole, a potent antisecretory drug. The genomic DNA ofHpylori was studied by electrophoretic separation of restriction endonuclease fragments followed by rRNA gene hybridisa...
