The Diversity of Lipopolysaccharide (O) and Capsular Polysaccharide (K) Antigens of Invasive Klebsiella pneumoniae in a Multi-Country Collection

Frontiers in Microbiology, 2020
Klebsiella pneumoniae is a common cause of sepsis and is particularly associated with healthcare-associated infections. New strategies are needed to prevent or treat infections due to the emergence of multi-drug resistant K. pneumoniae.

Genetic analysis of the capsular biosynthetic locus from all 90 pneumococcal serotypes. [PDF]

PLoS Genetics, 2006
Several major invasive bacterial pathogens are encapsulated. Expression of a polysaccharide capsule is essential for survival in the blood, and thus for virulence, but also is a target for host antibodies and the basis for effective vaccines ...

Sequence diversity within the capsular genes of Streptococcus pneumoniae serogroup 6 and 19. [PDF]

PLoS ONE, 2011
The main virulence factor of Streptococcus pneumoniae is the capsule. The polysaccharides comprising this capsule are encoded by approximately 15 genes and differences in these genes result in different serotypes. The aim of this study was to investigate

Capsular typing of Haemophilus influenzae with a DNA probe

Molecular and Cellular Probes, 1991
We describe the use of a DNA probe for genotyping clinical isolates of Haemophilus influenzae. The probe, containing capsulation genes, differentiates between the six Haemophilus serotypes in a Southern blotting procedure. It also hybridizes with a distinctive pattern to DNA from capsule-deficient mutants of serotype b strains, while failing to ...

Whole genome sequencing of Klebsiella pneumoniae clinical isolates sequence type 627 isolated from Egyptian patients.

PLoS ONE, 2022
Klebsiella pneumoniae is considered a threat to public health especially due to multidrug resistance emergence. It is largely oligoclonal based on multi-locus sequence typing (MLST); in Egypt, ST 627 was recently detected.

Characterization of Streptococcus suis capsular type 2 haemolysin [PDF]

Microbiology, 1995
The production of a haemolysin by Streptococcus suis capsular type 2 was investigated. Human group O erythrocytes were the most susceptible, followed by horse, sheep, cow and pig red blood cells, which exhibited similar susceptibilities; rabbit erythrocytes were the least susceptible.

Comparison of counterimmunoelectrophoresis and the capsular reaction test for typing of pneumococci [PDF]

Journal of Clinical Microbiology, 1980
The capsular reaction test is recommended as the method of choice for typing of pneumococci. Counterimmunoelectrophoresis also works in most cases, but has the following definite drawbacks. (i) The polysaccharide type antigens of types 7F, 7A, 14, 33F, 33A, and 37 are neutral and therefore do not form precipitates when conventional buffers are used ...
