[REP-PCR analysis of Helicobacter pylori clinical strains].
Helicobacter pylori strains isolated from 20 gastritis patients and 20 peptic ulcer patients was genotyped by REP-PCR and was clustered with SAS software. These strains are divided into two categories according to their genotype. But the rate of the two sources of strain in the two categories shows no apparent difference(P approximately 0.1), indicating that there is no significant close relationship between the genotype and the pathogenicity.
