Low pH effect on the gastric pathogen Helicobacter pylori: time course
Summary:
Analysis of Helicobacter pylori strain G27 after 30, 60, 90, and 120 minutes of pH 5.0 acid exposure. Results provide insight into the mechanisms employed by the bacterium that help it adapt to the hostile environment of the human stomach.
