Helicobacter pylori flagellar sheaths were isolated by sucrose density-gradient centrifugation and analysed by electronmicroscopy, SDS-PAGE and gas-liquid chromatography. Electronmicroscopy of thin sections of flagella showed an internal electron-dense filament and a surrounding flagellar sheath with the typical bilayer structure of a membrane. The(More)

Screening of a genomic library of H. pylori with an oligonucleotide(More)
