The adhesion of Lactobacillus rhamnosus GG to human enterocyte-like Caco-2 cells was not inhibited by eight carbohydrates tested, namely N-acetyl-glucosamine, galactose, glucose, fructose, fucose, mannose, methyl-alpha-D-mannopyranoside and sucrose. The degree of hydrophobicity predicted the adhesion of L. rhamnosus GG to Caco-2 cells. L. rhamnosus GG, however, was able to compete with Escheric...

The molecular mechanisms of Bordetella virulence are now well understood, and many virulence factors have been identified and characterized at the molecular level. These virulence factors can be grouped into two major categories: adhesins, such as filamentous hemagglutinin, pertactin and fimbriae, and toxins, such as pertussis toxin, adenylate cyclase, dermonecrotic toxin and tracheal cytotoxin...

Protein secretion is a basic cellular function found in organisms of all kingdoms of life. Gram-negative bacteria have evolved a remarkable number of pathways for the transport of proteins across the cell envelope. The secretion systems fulfill general cellular functions but are also essential for pathogenic bacteria during the interaction with eukaryotic host cells. Secretion systems range fro...

475 Abstract: The pattern of distribution of fibronectin adhesins on yeast and hyphalform Candida albicans was studied with goldlabelled fibronectin and transmission electron microscopy. The germ-tube parts of the hyphal-form cells were the major binding sites for gold-labelled fibronectin, and the attached yeast-cell parts and yeast-form cell remained unlabelled. Therefore, the walls of the ge...

MOTIVATION Trimeric autotransporter adhesins (TAAs), such as Yersinia YadA, Neisseria NadA, Moraxella UspAs, Haemophilus Hia and Bartonella BadA, are important pathogenicity factors of proteobacteria. Their high sequence diversity and distinct mosaic-like structure lead to difficulties in the annotation of their sequences. These stem from the large number of short repeats, the presence of compo...

conclusions these results indicate that the pcr method is a powerful genotypic assay for the detection of adhesin-encoding operons. thus, this assay can be recommended for clinical use to detect virulent urinary e. coli strains, as well as epidemiological studies. materials and methods a total of 100 upec isolates were obtained from urine samples of patients with uti. the prevalence of 5 virule...
