TL;DR: The overall aim of this review is to examine methods for the capture and detection of AgNPs, potential toxicity and transmission routes in the aquatic environment.
Journal ArticleDOI
Molecular mimicry of host structures by bacterial lipopolysaccharides and its contribution to disease
TL;DR: The core oligosaccharides of low-molecular-weight lipopolysaccharide (LPS) of pathogenic Neisseria spp.
Journal ArticleDOI

TL;DR: Genetic analyses of genes involved in the biosynthesis of the outer core of C. jejuni 81-176 revealed the presence of a homopolymeric tract of G residues within a gene encoding CgtA, an N-acetylgalactosaminyltransferase that corresponded to a change in LOS structure from GM2 to GM3 ganglioside mimicry.
Journal ArticleDOI
Sialylation of Lipooligosaccharide Cores Affects Immunogenicity and Serum Resistance of Campylobacter jejuni
TL;DR: Mutation of genes encoding proteins with homology to a sialyl transferase (cstII) and a putative N-acetylmannosamine synthetase (neuC1) resulted in LOS cores intermediate in electrophoretic mobility between that of wild type and the mutants lacking NeuNAc, loss of reactivity with CT, and a reduced immunoreactivity with hyperimmune antiserum.
Journal ArticleDOI
Lipopolysaccharides from Campylobacter jejuni O:41 strains associated with Guillain-Barré syndrome exhibit mimicry of GM1 ganglioside.
TL;DR: The aim of the study was to determine the structure of the core oligosaccharide of the lipopolysaccharide (LPS) of C. jejuni serotype O:41, a serotype rarely associated with the development of GBS, and to determine if the LPS shares similar epitopes with any of the major human gangliosides.
