title: Categorization of clinical isolates of Helicobacter pylori on the basis of restriction digest analyses of polymerase chain reaction-amplified ureC genes.
abstract: Restriction endonuclease analyses of a 1.1-kb polymerase chain reaction-amplified portion of the ureC gene from Helicobacter pylori were used to group or to differentiate 21 clinical isolates. Isolates were placed into 4 groups after HindIII digestion alone, and placement was expanded into 15 groups after isolates were digested with AluI and PvuI.
