The essential role for both flaA and flaB in establishment of persistent colonization has been previously demonstrated by Eaton et al., who showed that aflagellate H. pylori strains only transiently colonized gnotobiotic piglets.59 Ultrastructural studies have demonstrated that the H. pylori flagellum is cloaked by a sheath that is an extension of the bacterial outer membrane, which likely protects the acid-labile flagellar structure from gastric contents.62 Similar to urease production, motility is required for persistent infection and McGee and colleagues have reported that FlbA, a component of the flagellar secretion apparatus that regulates flagellar biosynthesis, also mediates urease activity;63 thus, FlbA may couple urease production and motility, bacterial phenotypes that are necessary for the establishment and maintenance of gastric colonization.

Pharmaceuticals (Basel). Another adherence-related H. pylori product is HopZ, and inactivation of the gene encoding this protein dramatically decreases the ability of H. pylori to bind gastric epithelial cells in vitro.80 Similarly, inactivation of genes encoding AlpA and AlpB attenuates binding of H. pylori to epithelial cells, indicating that these molecules function as adhesins.81 The genes encoding HopZ, AlpA, and AlpB are present in most, if not all, H. pylori isolates,80,81 suggesting that they may have important roles in colonization.
