Comparative ultrastructural and functional studies of Helicobacter pylori and Helicobacter mustelae flagellin mutants: both flagellin subunits, FlaA and FlaB, are necessary for full motility in Helicobacter species

Abstract excerpt

Helicobacter mustelae causes chronic gastritis and ulcer disease in ferrets. It is therefore considered an important animal model of human Helicobacter pylori infection. High motility even in a viscous environment is one of the common virulence determinants of Helicobacter species. Their sheathed flagella contain a complex filament that is composed of two distinctly different flagellin subunits, FlaA and FlaB,...
