Conformational and Immunogenicity Studies of the Shigella flexneri Serogroup 6 O-Antigen: The Effect of O-Acetylation

open access: yesVaccines, 2021
The pathogenic bacterium Shigella is a leading cause of diarrheal disease and mortality, disproportionately affecting young children in low-income countries. The increasing prevalence of antibiotic resistance in Shigella necessitates an effective vaccine,

Foot-and-mouth disease virus O/ME-SA/Ind 2001 lineage outbreak in vaccinated Holstein Friesian cattle in Saudi Arabia in 2016

open access: yesVeterinary Quarterly, 2018
Background: Foot-and-mouth disease virus (FMDV) is a highly contagious viral infection of large ruminants. Despite the massive application of vaccines against FMDV, several outbreaks are still being reported in Africa and Asia.

Subdistrict-Level Reproductive Number for Foot and Mouth Disease in Cattle in Northern Thailand

open access: yesFrontiers in Veterinary Science, 2021
Foot and mouth disease (FMD) is an important contagious transboundary disease that causes a significant economic loss for several countries. The FMD virus (FMDV) can spread very rapidly by direct and indirect transmission among susceptible animals.

Evaluation of a Proteus rettgeri O-serotyping system for epidemiological investigation [PDF]

open access: yesJournal of Clinical Microbiology, 1976
An evaluation of the serotyping system for Proteus rettgeri has been performed through its application to 561 human isolates of this species. Of these, 545 were typable and could be separated into 58 O serotypes. A group of isolates from one hospital, and clinically implicated in cross-infections, was found to belong the same O serotype, confirming the

O‐Linked GlcNAc in serotype‐2 adenovirus fibre [PDF]

open access: yesEuropean Journal of Biochemistry, 1989
Serotype‐2 adenovirus fibre is shown to possess an O‐linked GlcNAc residue and to have affinity for wheat germ agglutinin. The cytoplasmic and nuclear fibres are both glycosylated. Glycosylation seems to take place in the cytoplasm since most of the [14C]GlcN‐labelled fibre is found in this compartment, little label being associated with the microsomes.

Spatial pattern of foot-and-mouth disease virus serotypes in North Central Nigeria [PDF]

open access: yesVeterinary World, 2017
Aim: This study aimed to determine the foot-and-mouth disease virus (FMDV) serotypes circulating, the prevalence of FMDV serotypes, and the spatial distribution of FMDV among sedentary and pastoral cattle herds in the North-Central Nigeria.

Identification of critical residues of O-antigen-modifying O-acetyltransferase B (OacB) of Shigella flexneri

open access: yesBMC Molecular and Cell Biology, 2022
Background Shigellosis is an acute gastrointestinal disease caused primarily by the bacterium Shigella flexneri. Upon ingestion, S. flexneri initiates a serotype-specific immune response that targets the O-antigen of the pathogen’s lipopolysaccharide.

Cross-Serotype Reactivity of ELISAs Used to Detect Antibodies to the Structural Proteins of Foot-and-Mouth Disease Virus

open access: yesViruses, 2022
Antibodies to the foot-and-mouth disease virus (FMDV) capsid induced by infection or vaccination can provide serotype-specific protection and be measured using virus neutralization tests and viral structural-protein (SP-)ELISAs. Separate tests are needed

Development of an O-Antigen Serotyping Scheme for Cronobacter sakazakii [PDF]

open access: yesApplied and Environmental Microbiology, 2011
ABSTRACT Cronobacter sakazakii is an opportunistic pathogen that can cause severe infections. Serotyping provides a basis for the categorization of bacterial strains and is an important tool for epidemiological and surveillance purposes.
