Abstract excerpt

Nine strains of Helicobacter pylori have been isolated exhibiting spontaneous mutations with a loss of catalase activity. Growth characteristics in vitro were unaffected by the mutation showing that catalase is not essential for growth of Helicobacter pylori. Parent strains and mutants could not be distinguished morphologically from each other when compared by electron microscopy. Restriction endonuclease...
