Abstract excerpt
BACKGROUND: The discovery of a highly active catalase in Helicobacter pylori that in some strains may lose its activity has generated strong scientific interest. We have characterized a spontaneous catalase-negative isolate of H. pylori (UNSW-RU1) and sequenced katA in the parent strain and the p...
