Intracellular redox status and antibiotic resistance in enterogastric micro-aerophilic bacteria: evidence for the 'scavenging of oxygen' hypothesis.


Metronidazole and glutathione reduction activities were measured in situ in the micro-aerophilic bacteria Campylobacter coli and Helicobacter pylori employing 14N- and 1H-nuclear magnetic resonance spectroscopy. The properties of these enzyme activities were investigated in matched pairs of strains with sensitive and resistant phenotypes to the… (More)
