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

Serotype-converting bacteriophages and O-antigen modification in Shigella flexneri
O-antigen modification (serotype conversion) in Shigella flexneri, which is an important virulence determinant, is conferred by temperate bacteriophages. Several serotype-converting phages have been isolated and preliminary characterization has identified the genes involved in O-antigen modification, and has also provided insight into the molecular ...

Designing one-step reverse transcriptase loop-mediated isothermal amplification for serotype O foot-and-mouth disease virus detection during the 2022 outbreak in East Java, Indonesia [PDF]
Background and Aim: Various methods can detect foot-and-mouth disease (FMD) in cows, but they necessitate resources, time, costs, laboratory facilities, and specific clinical specimen submission, often leading to FMD virus (FMDV) diagnosis delays.

O and H serotyping of Pseudomonas cepacia [PDF]
Procedures for the preparation, absorption, and titration of Pseudomonas cepacia O and H rabbit antisera are described. Seven O antigens (O1 to O7) for the slide agglutination test and five H antigens (H1, H3, H5, H6, and H7) for the agglutination and H immobilization tests were determined. Nearly 300 strains of P.

Amino acid diversity of antigenic sites of Iranian type O foot-and-mouth disease virus [PDF]
Foot-and-mouth disease (FMD) is a major cause of endemic outbreaks in livestock in Iran. In this study, clinical field samples of foot-and-mouth disease virus were collected from an outbreak in Khorasan Razavi Province during April and August of 2010 ...

O-antigen specificities of the serotype strains of Serratia marcescens [PDF]
O antigens of the 24 O-serotype strains of Serratia marcescens were investigated in dot enzyme immunoassay with whole-cell antigens and by immunoblotting with lipopolysaccharide (LPS) antigens. Three pairs of strains, O2/O3, O6/O7, and O12/O14, had indistinguishable LPS antigens, despite having distinct specificities in agglutination tests with whole ...

Identification and characterization of a novel Shigella flexneri serotype Yv in China. [PDF]
Shigella flexneri is the major cause of bacterial shigellosis in developing countries. S. flexneri is divided into at least 19 serotypes, the majority of which are modifications of the same basic O-antigen by glucosylation and/or O-acetylation of its ...

A novel plasmid-encoded serotype conversion mechanism through addition of phosphoethanolamine to the O-antigen of Shigella flexneri. [PDF]
Shigella flexneri is the major pathogen causing bacillary dysentery in developing countries. S. flexneri is divided into at least 16 serotypes based on the combination of antigenic determinants present in the O-antigen.
