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 ...

Biotechnology Letters, 2016 To determine whether the G-H loop of foot-and-mouth disease virus (FMDV) serotype O can function as a target structure to harbour and display serotype Asia1 antigenic epitope at the surface.Using reverse genetics, FMDV serotype O IND R2/1975 displaying a FMDV serotype Asia1 B cell epitope at the capsid surface was constructed.

O and H serotyping of Pseudomonas cepacia [PDF]
Journal of Clinical Microbiology, 1983 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.

O-antigen specificities of the serotype strains of Serratia marcescens [PDF]
Journal of Clinical Microbiology, 1989 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 ...

A novel plasmid-encoded serotype conversion mechanism through addition of phosphoethanolamine to the O-antigen of Shigella flexneri. [PDF]
PLoS ONE, 2012 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.

Molecular characterization of foot-and-mouth disease viruses collected from Northern and Central Ethiopia during the 2018 outbreak [PDF]
Veterinary World, 2020 Background and Aim: Foot-and-mouth disease (FMD) is endemic in several developing countries and affects poor farmers through loss of production, death of diseased animals, and loss of animal byproducts. Forty-three samples were collected from 12 sites of

Genome analysis of a highly virulent serotype 1 strain of streptococcus pneumoniae from West Africa [PDF]
, 2012 Streptococcus pneumoniae is a leading cause of pneumonia, meningitis, and bacteremia, estimated to cause 2 million deaths annually. The majority of pneumococcal mortality occurs in developing countries, with serotype 1 a leading cause in these areas.
