Pylori in Response to Low pH and Iron Limiting Growth Conditions Nature Precedings Ananya Gupta; Sergey Ustinov; Kaveh Mashayekhi; Anthony P. Moran. Establishing a successful infection within the gastric environment and its varied and changing niches requires adaptation achieved through regulation of bacterial gene expression. In the gastric environment in addition to the low pH Helicobacter pylori is required to adapt to conditions of iron limitation. In this study, we used cDNA microarrays to identify genes whose expression was altered when the bacterium was grown under differing conditions of pH (5 versus 7) and iron limitation. cDNA microarray analyses following exposure to different growth conditions were carried out for three H. pylori strains 26695 (gastritis-associated), J99 (ulcer-associated) and AG-1 (atrophic gastritis-associated). Genes were identified whose expression was acid pH-dependent... Tipo: Poster Palavras-chave: Microbiology.
