The bacterium Helicobacter pylori is the causative agent for peptic ulcer disease. Bacterial
adherence to the human gastric epithelial lining is mediated by the fucosylated Lewis b
(Leb) histo-blood group antigen. The Leb-binding adhesin, BabA, was purified by receptor
activity–directed affinity tagging. The bacterial Leb-binding phenotype was associated with
the presence of the cag pathogenicity island among clinical isolates of H. pylori. A vaccine
strategy based on the BabA adhesin might serve as a means to target the virulent type I …
