Abstract: | Molecular hydrogen is produced in the large intestine of animals due to the fermentation reactions of sugar catabolism. The gastric pathogen Helicobacter pylori and the liver pathogen Helicobacter hepaticus have the capacity to use molecular hydrogen as a respiratory substrate. The amount of the gas within tissues colonized by these pathogens is ample, and use of H2 significantly increases the stomach colonization ability of H. pylori. |
