Abstract
Helicobacter pylori urease subunit genes in 383 isolates from 10 countries were investigated by PCR-restriction fragment length polymorphism (HaeIII) analysis. Eighty-two different ureAB profiles were documented by reference to known sequences. Variation among 51% of strains was accounted for by 10 predominant patterns, which provided a unique framework for categorizing isolates with geographically diverse origins.
