Construction of isogenic urease-negative mutants of Helicobacter pylori by allelic exchange.

Isogenic urease-negative mutants of Helicobacter pylori were constructed by allelic replacement. A region of cloned H. pylori DNA containing the structural urease genes (ureA and ureB) was disrupted by insertion of a mini-Tn3-Km transposon. Electrotransformation of H. pylori cells with kanamycin-ure...
