BACKGROUND AND OBJECTIVE The cell-surface lipooligosaccharide (LOS) of Treponema denticola possesses several biological properties. The aim of this study was to investigate the binding properties of T. denticola LOS to extracellular matrix (ECM) proteins, mucosal cells, and oral bacteria. DESIGN LOS was isolated from T. denticola and labeled with tritium. Tritium-labeled LOS was placed in ECM...
Campylobacter jejuni strains exhibit significant variation in the genetic content of the lipooligosaccharide (LOS) biosynthesis loci with concomitant differences in LOS structure. The C. jejuni LOS loci have been grouped into six classes based on gene content and organization. Utilizing PCR amplifications of genes from these loci, we were able to classify a majority (80%) of the LOS biosynthesi...
Glycomics is a rapidly growing field that focuses on the structure and function of carbohydrates (glycans) in biological systems. Glycan interactions play a major role in infectious disease, at all stages of colonisation and disease progression. Neisseria meningitidis, the cause of meningococcal sepsis and meningitis, and Neisseria gonorrhoeae, which causes the sexually transmitted infection go...
We developed an enzyme-linked immunosorbent assay-based assay to assess Haemophilus ducreyi binding to extracellular matrix (ECM) proteins. H. ducreyi 35000HP bound to fibronectin, laminin, and type I and III collagen but not to type IV, V, or VI collagen or elastin. Isogenic strains with mutations in ftpA or losB bound as well as the parent, suggesting that neither pili nor full-length lipooli...
Sequencing and comparative genome analysis of four strains of Campylobacter including C. lari RM2100, C. upsaliensis RM3195, and C. coli RM2228 has revealed major structural differences that are associated with the insertion of phage- and plasmid-like genomic islands, as well as major variations in the lipooligosaccharide complex. Poly G tracts are longer, are greater in number, and show greate...
