IMMUNOCHEMISTRY OF THE CAPSULAR POLYSACCHARIDE OF AN Acinetobacter [PDF]

Proceedings of the National Academy of Sciences, 1969
The capsular polysaccharide of a strain, BD4, of Acinetobacter calco-aceticus (A.c-a), composed of L-rhamnose and D-glucose, 4:1, precipitates all streptococcal group B antisera tested, as well as streptococcal group G antisera and antipneumococcal (Pn) type XXIII serum.

Determination of the binding affinities of Neisseria meningitidis serogroup W capsule polymerase with two nucleotide sugar substrates

BMC Research Notes, 2018
Objective Meningococcal meningitis is a public health burden. Immunization strategies have reduced global incidence of the disease. Glycoconjugate vaccines are the most effective type of vaccine to combat most causes of meningococcal meningitis.

ATP-Binding Cassette (ABC) Transporters and Antibiotic Resistance: Specialized Systems for Capsular Polysaccharide Export in Gram-Negative Pathogens

Polysaccharides
ABC transporters are a large family of proteins that mediate the export or import of a variety of molecules, including capsular polysaccharides. The capsules are an important virulence factor that protect bacteria from host immune system attacks ...

Two variants among Haemophilus influenzae serotype b strains with distinct bcs4, hcsA and hcsB genes display differences in expression of the polysaccharide capsule

BMC Microbiology, 2008
Background Despite nearly complete vaccine coverage, a small number of fully vaccinated children in the Netherlands have experienced invasive disease caused by Haemophilus influenzae serotype b (Hib).

Capsular Polysaccharide of Group AStreptococcus [PDF]

Microbiology Spectrum, 2014
ABSTRACT Most clinical isolates of Streptococcus pyogenes elaborate a capsular polysaccharide, which is composed of hyaluronic acid, a high-molecular-mass polymer of alternating residues of N -acetyl glucosamine and glucuronic acid ...

Concentration of anti-pneumococcal capsular polysaccharide IgM, IgG and IgA specific antibodies in adult blood donors

Practical Laboratory Medicine, 2016
Objectives: Anti-pneumococcal capsular polysaccharide (PCP) IgM, IgG and IgA ELISAs have been developed to aid assessment of the adaptive immune system. The relationship between the concentrations of PCP IgM, IgG, and IgA was investigated.

Capsules from pathogenic and non-pathogenic Cryptococcus spp. manifest significant differences in structure and ability to protect against phagocytic cells. [PDF]

PLoS ONE, 2012
Capsule production is common among bacterial species, but relatively rare in eukaryotic microorganisms. Members of the fungal Cryptococcus genus are known to produce capsules, which are major determinants of virulence in the highly pathogenic species ...

Pneumococcal Capsular Polysaccharide Immunity in the Elderly

Clinical and Vaccine Immunology, 2017
ABSTRACT Immunity to pneumococcal infections is impaired in older people, and current vaccines are poorly protective against pneumococcal disease in this population. Naturally acquired immunity to pneumococcal capsular polysaccharides develops during childhood and is robust in young adults but deteriorates with advanced age.

THE CAPSULAR POLYSACCHARIDE OF PNEUMOCOCCUS TYPE IX [PDF]

The Journal of Experimental Medicine, 1966
The capsular polysaccharide of Type IX pneumococcus contains D-glucose, N-acetyl-D-glucosamine, and D-glucuronic acid. Complete hydrolysis is difficult. All of the N-acetylglucosamine is resistant to oxidation by periodate, but the other two sugars are degraded in part. Chemical and quantitative serological data are consistent with the linkage of two D-
