To determine the existence of an acid stress response in Helicobacter pylori the global changes in the proteins synthesized by the bacterium when subjected to an acid stress were studied. H. pylori ATCC43504 previously ...

Background: Helicobacter pylori colonizes the acid environment of the gastric mucosa. Like other enteric bacterial pathogens, including Salmonella enterica, which must survive a brief exposure to that environment, H. pylori ...

The acid tolerance response in Lactobacillus acidophilus CRL 639, induced at pH 4.2 for 15 min, is mediated by the cell membrane F1-F0 ATPase. The specific activity of the enzyme was induced 1.6-fold after acid adaptation ...

To determine whether glucose tolerance varies throughout the day in people with impaired glucose tolerance (IGT). We studied 15 healthy IGT, and 18 matched normal glucose tolerant (NGT) individuals. Blood samples were taken ...
