Development of a scheme for genotyping Helicobacter pylori based on allelic variation in urease subunit genes.

R J Owen1, E R Slater, J Xerry, T M Peters, E L Teare, A Grant.   

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.
