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

mBio, 2019
O-antigens are glycopolymers in lipopolysaccharides expressed on the cell surface of Gram-negative bacteria. Variability in the O-antigen structure constitutes the basis for the establishment of the serotyping schema. We pursued a two-pronged approach to

Salmonella Typhimurium derived OMV nanoparticle displaying mixed heterologous O-antigens confers immunogenicity and protection against STEC infections in mice [PDF]

Microbial Cell Factories
Shiga toxin-producing Escherichia coli (STEC) is one of the major pathogens responsible for severe foodborne infections, and the common serotypes include E. coli O157, O26, O45, O103, O111, O121, and O145.

Diversity of O Antigens within the Genus Cronobacter: from Disorder to Order. [PDF]

Appl Environ Microbiol, 2015
Cronobacter species are Gram-negative opportunistic pathogens that can cause serious infections in neonates. The lipopolysaccharides (LPSs) that form part of the outer membrane of such bacteria are possibly related to the virulence of particular ...

Genetics and evolution of the Salmonella galactose-initiated set of o antigens. [PDF]

PLoS ONE, 2013
This paper covers eight Salmonella serogroups, that are defined by O antigens with related structures and gene clusters. They include the serovars that are now most frequently isolated.

Tumor-associated Tn and STn antigens: from molecular mechanism to precision diagnosis and treatment [PDF]

Frontiers in Immunology
BackgroundAbnormal protein glycosylation is a key feature of tumors. Among the modifications, Tn antigen (GalNAcα1-Ser/Thr) and its sialylated derivative, STn antigen (Neu5Acα2-6GalNAcα1-O-Ser/Thr), are prominent tumor-associated carbohydrate antigens ...

Immunogenicity evaluation of altSonflex1-2–3 Shigella vaccine across mice, rats, and rabbits to inform human translational insights [PDF]

Frontiers in Immunology
Shigella, a leading cause of bacillary dysentery, represents a significant global health challenge, particularly in low- and middle-income countries. Shigellosis predominantly affects children under the age of five and is associated with high morbidity ...

Antigenic Relationships Between Escherichia coli O Antigens O 149 to O 163 and Shigella O Antigens [PDF]

International Journal of Systematic Bacteriology, 1976
O antigens O 149 to O 163 are recent additions to the Escherichia coli antigenic scheme. Their antigenic relationships with Shigella serovars were examined. O antigen identity was demonstrated between E. coli O 149 and Shigella boydii 1 and between E. coli O 152 and provisional Shigella serovar 3341-55.

Shigella Flexneri Serotypes: O-antigen Structure, Serotype Conversion, and Serotyping Methods

Oman Medical Journal, 2023
Shigella flexneri is the most common cause of shigellosis in developing countries. Up to now, 23 serotypes of S. flexneri have been reported. Different serotypes result from the addition of acetyl, glucosyl, or phosphatidylethanolamine groups on the O ...

Association of the blood groups with mostly public Diseases

Kufa Journal for Nursing Sciences, 2021
The ABO blood group system is identified in 1900. Its principle that antigens as sugars physically exposed on the exterior of red blood cells *RBCs* differ between individuals, who have immunological tolerance only toward what occurs in their own bodies.

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.
