Structure and genetics of Escherichia coli O antigens. [PDF]

FEMS Microbiol Rev, 2020
Escherichia coli includes clonal groups of both commensal and pathogenic strains, with some of the latter causing serious infectious diseases. O antigen variation is current standard in defining strains for taxonomy and epidemiology, providing the basis ...

Reinvestigation of the structure of Brucella O-antigens. [PDF]

Carbohydr Res, 2013
O-Specific polysaccharides of Brucella contain two antigenic determinants, called A and M. Most of the strains express epitope A with a small amount of epitope M, whereas Brucella melitensis strain 16 M expresses longer polymer consisting mostly of M-type epitopes.

Systems Biology and Pangenome of Salmonella O-Antigens. [PDF]

mBio, 2019
Lipopolysaccharides are a major component of the outer membrane in Gram-negative bacteria. They are composed of a conserved lipid structure that is embedded in the outer leaflet of the outer membrane and a polysaccharide known as the O-antigen.

Citrobacter O-antigens: structure of the O-antigenic polysaccharide from Citrobacter sp. 396 [PDF]

Journal of Bacteriology, 1978
The structure of the O-specific polysaccharide moiety of the lipopolysaccharide from Citrobacter 396 was elucidated by composition, methylation, and periodate oxidation studies. The repeating unit consists of four 2-linked mannoses and one 3-linked N-acetylglucosamine.

Lipophilic O-antigens in Rhodospirillum tenue [PDF]

Journal of Bacteriology, 1977
Lipopolysaccharides of eight wild-type strains of the phototrophic bacterium Rhodospirillum tenue have been analyzed. All of the lipopolysaccharides are highly lipophilic. The compositions of preparations obtained by the phenol-water or by the phenol-chloroform-petroleum ether procedure are very similar. The polysaccharide moiety, obtained by mild acid

Mechanism of O-antigen distribution in lipopolysaccharide [PDF]

Journal of Bacteriology, 1990
O-antigen units are nonuniformly distributed among lipid A-core molecules in lipopolysaccharide (LPS) from gram-negative bacteria, as revealed by polyacrylamide gel electrophoresis in sodium dodecyl sulfate; the actual distribution patterns are complex, multimodal, and strain specific.

Identification of the lipopolysaccharide O‐antigen biosynthesis priming enzyme and the O‐antigen ligase in Myxococcus xanthus: critical role of LPS O‐antigen in motility and development [PDF]

Molecular Microbiology, 2019
SummaryMyxococcus xanthus is a model bacterium to study social behavior. At the cellular level, the different social behaviors of M. xanthus involve extensive cell–cell contacts. Here, we used bioinformatics, genetics, heterologous expression and biochemical experiments to identify and characterize the key enzymes in M.

Immunity to Intracellular Salmonella Depends on Surface-associated Antigens [PDF]

, 2012
Invasive Salmonella infection is an important health problem that is worsening because of rising antimicrobial resistance and changing Salmonella serovar spectrum.

The Structural Diversity of Carbohydrate Antigens of Selected Gram-Negative Marine Bacteria

Marine Drugs, 2011
Marine microorganisms have evolved for millions of years to survive in the environments characterized by one or more extreme physical or chemical parameters, e.g., high pressure, low temperature or high salinity.

Boosting antibody responses to Plasmodium falciparum merozoite antigens in children with highly seasonal exposure to infection. [PDF]

, 2010
Longitudinal cohort studies are important to describe the dynamics of naturally acquired antibody response profiles to defined Plasmodium falciparum malaria antigens relative to clinical malaria episodes.
