Expression of histo-blood group antigens by lipopolysaccharides of Helicobacter pylori strains from Asian hosts: the propensity to express type 1 blood-group antigens (2000)

Monteiro, Mario A., Zheng, Peng-yuan, Ho, Bow, Yokota, Shin-ichi, Amano, Ken-ichi, Pan, Zhi-jun, ...

Past studies have shown that the cell surface lipopolysaccharides (LPSs) of the ubiquitous human gastric pathogen Helicobacter pylori (a type 1 carcinogen) isolated from people residing in Europe and...

Prevalence of O1/K1- and O2/K3-Reactive Actinobacillus suis in Healthy and Diseased Swine

Slavić, ĐurĐa, Toffner, Tania L., Monteiro, Mario A., Perry, Malcolm B., MacInnes, Janet I.

A cell surface antigen-typing system was devised for the swine pathogen Actinobacillus suis and used to examine the prevalence of different lipopolysaccharide (O) types in healthy and diseased pigs....

Assembly of the K40 Antigen in Escherichia coli: Identification of a Novel Enzyme Responsible for Addition of l-Serine Residues to the Glycan Backbone and Its Requirement for K40 Polymerization

Amor, Paul A., Yethon, Jeremy A., Monteiro, Mario A., Whitfield, Chris

Escherichia coli O8:K40 coexpresses two distinct lipopolysaccharide (LPS) structures on its surface. The O8 polysaccharide is a mannose homopolymer with a trisaccharide repeat unit and is synthesized...

Phase Variation in Helicobacter pylori Lipopolysaccharide due to Changes in the Lengths of Poly(C) Tracts in α3-Fucosyltransferase Genes

Appelmelk, Ben J., Martin, Steve L., Monteiro, Mario A., Clayton, Chris A., McColm, Andrew A., Zheng, Pengyuan, ...

The lipopolysaccharide (LPS) of Helicobacter pylori expresses the Lewis x (Lex) and/or Ley antigen. We have shown previously that H. pylori LPS displays phase variation whereby an Lex-positive strain...

Phase Variation in H Type I and Lewis a Epitopes of Helicobacter pylori Lipopolysaccharide

Appelmelk, Ben J., Martino, M. Celeste, Veenhof, Eveline, Monteiro, Mario A., Maaskant, Janneke J., Negrini, Riccardo, ...

Helicobacter pylori NCTC 11637 lipopolysaccharide (LPS) expresses the human blood group antigens Lewis x (Lex), Ley, and H type I. In this report, we demonstrate that the H type I epitope displays...

Mutation of waaC, Encoding Heptosyltransferase I in Campylobacter jejuni 81-176, Affects the Structure of both Lipooligosaccharide and Capsular Carbohydrate

Kanipes, Margaret I., Papp-Szabo, Erzsebet, Guerry, Patricia, Monteiro, Mario A.

Campylobacter jejuni 81-176 lipooligosaccharide (LOS) is composed of two covalently linked domains: lipid A, a hydrophobic anchor, and a nonrepeating core oligosaccharide, consisting of an inner and...

Genetic Analysis of Lipooligosaccharide Core Biosynthesis in Campylobacter jejuni 81-176▿

Kanipes, Margaret I., Tan, Xuan, Akelaitis, Aurel, Li, Jiajun, Rockabrand, David, Guerry, Patricia, ...

We report isolation and characterization of Campylobacter jejuni 81-176 lgtF and galT lipooligosaccharide (LOS) core mutants. It has been suggested that the lgtF gene of C. jejuni encodes a...

Characterization of Two Campylobacter jejuni Strains for Use in Volunteer Experimental-Infection Studies▿ †

Poly, Frédéric, Read, Timothy D., Chen, Yu-Han, Monteiro, Mario A., Serichantalergs, Oralak, Pootong, Piyarat, ...

The development of vaccines against Campylobacter jejuni would be facilitated by the ability to perform phase II challenge studies. However, molecular mimicry of the lipooligosaccharide (LOS) of most...
