Abstract

We examined the competition of binding of Lactobacillus reuteri and Helicobacter pylori to gangliotetraosylceramide (asialo-GM1) and sulfatide which are putative glycolipid receptor molecules of H. pylori, and identified a possible sulfatide-binding protein of the L. reuteri strain. Among nine L. reuteri strains, two (JCM1081 and TM105) were shown to bind to asialo-GM1 and sulfatide, and to inhibit binding of H. pylori to both glycolipids by a thin layer chromatogram-overlay assay using biotin-labeled bacterial cells. The extract from the bacterial cells of strain TM105 with several detergents, including octyl beta-D-glucopyranoside, retained binding to both glycolipids and also inhibited H. pylori binding, suggesting that a binding inhibitor(s) is associated with the bacterial cell surface. When the cell extract was applied to the agarose gel immobilized galactose 3-sulfate corresponding to the structure of sugar moieties of sulfatide, an approximately 47-kDa protein was found to bind to the gel. This observation strongly suggested that inhibition by selected L. reuteri strains help to prevent infection in an early stage of colonization in H. pylori and proposed that L. reuteri strains sharing glycolipid specificity with H. pylori have a potential as probiotics.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
