Abstract excerpt
BACKGROUND: We have investigated the possibility that the same patients may be colonized by Helicobacter pylori strains of different genotypes or phenotypes in the antrum as compared to in the duodenum. The strains were typed for DNA fingerprints, different lipopolysaccharides (LPS), and Lewis antigen expression on the O-side chains of LPS. MATERIALS AND METHODS: Polymerase chain reaction (PCR) amplifications...
