Rj. Owen et al., DEVELOPMENT OF A SCHEME FOR GENOTYPING HELICOBACTER-PYLORI BASED ON ALLELIC VARIATION IN UREASE SUBUNIT GENES, Journal of clinical microbiology (Print), 36(12), 1998, pp. 3710-3712
Helicobacter pylori urease subunit genes in 383 isolates from 10 count
ries were investigated by PCR restriction fragment length polymorphism
(HaeIII) analysis. Eighty-two different ureAB profiles were documente
d by reference to known sequences. Variation among 51% of strains was
accounted for by 10 predominant patterns, which provided a unique fram
ework for categorizing isolates with geographically diverse origins.
