Molecular hydrogen as an energy source for Helicobacter pylori.

Science (New York, N.Y.) - 29 Nov 2002

Olson Jonathan W, Maier Robert J

Abstract excerpt

The gastric pathogen Helicobacter pylori is known to be able to use molecular hydrogen as a respiratory substrate when grown in the laboratory. We found that hydrogen is available in the gastric mucosa of mice and that its use greatly increased the stomach colonization by H. pylori. Hydrogenase activity in H. pylori is constitutive but increased fivefold upon incubation with hydrogen. Hydrogen concentrations...
