Helicobacter pylori SabA adhesin in persistent infection and chronic inflammation.
Helicobacter pylori adherence in the human gastric mucosa involves specific bacterial adhesins and cognate host receptors. Here, we identify sialyl-dimeric-Lewis x glycosphingolipid as a receptor for… Expand

Lactic acid bacteria as probiotics.
A number of Lactobacillus species, Bifidobacterium sp, Saccharomyces boulardii, and some other microbes have been proposed as and are used as probiotic strains, i.e. live microorganisms as food… Expand

A new test based on 'salting out' to measure relative surface hydrophobicity of bacterial cells.
A simple method for quantification of the hydrophobic surface properties of bacteria is described. The method is based on precipitation of cells by salts, for instance (NH4)2SO4. The order in which… Expand

SabA Is the H. pylori Hemagglutinin and Is Polymorphic in Binding to Sialylated Glycans
Adherence of Helicobacter pylori to inflamed gastric mucosa is dependent on the sialic acid–binding adhesin (SabA) and cognate sialylated/fucosylated glycans on the host cell surface. By in situ… Expand

A collagen binding protein from Lactobacillus reuteri is part of an ABC transporter system?
The gene coding for a collagen binding protein from Lactobacillus reuteri NCIB 11951 was cloned and sequenced. A genomic lambda library was constructed and recombinant plaques were screened using… Expand

Prevalence of Helicobacter pylori infection among adult dyspeptic patients in Ethiopia
Abstract In developing countries such as Ethiopia, where chronic gastritis and peptic-ulcer disease are the most common endoscopic findings, it is important to study the association between… Expand

Identification of Helicobacter pylori and OtherHelicobacter Species by PCR, Hybridization, and Partial DNA Sequencing in Human Liver Samples from Patients with Primary Sclerosing Cholangitis or…
ABSTRACT Helicobacter pylori was identified in human liver tissue by PCR, hybridization, and partial DNA sequencing. Liver biopsies were obtained from patients with primary sclerosing cholangitis (n… Expand

Rapid detection of Helicobacter pylori in gastric biopsy material by polymerase chain reaction.
By using primers based on the sequence of a species-specific antigen of Helicobacter pylori (P. O'Toole, S.M. Logan, M. Kostrzynska. T. Wadström, and T.J. Trust, J. Bacteriol. 173:505-513, 1991), a… Expand

Binding to collagen by Yersinia enterocolitica and Yersinia pseudotuberculosis: evidence for yopA-mediated and chromosomally encoded mechanisms.
Binding of Yersinia enterocolitica and Yersinia pseudotuberculosis strains to type I, II, and IV collagens has been studied. Wild-type strains which harbored the 40- to 50-megadalton virulence… Expand

Inhibition of Helicobacter pylori infection by bovine milk glycoconjugates in a BAlb/cA mouse model.
The attachment of Helicobacter pylori to the human gastric mucosa is a complex process involving several specific structures recognised by the cell surface receptors. Sialylated multivalent high mol.… Expand
