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 ...

Capsular polysaccharides of cultured phototrophic biofilms [PDF]

Biofouling, 2009
Phototrophic biofilm samples from an Italian wastewater treatment plant were studied in microcosm experiments under varying irradiances, temperatures and flow regimes to assess the effects of environmental variables and phototrophic biomass on capsular exopolysaccharides (CPS).

Identification, characterization and immunogenicity of an O-antigen capsular polysaccharide of Francisella tularensis. [PDF]

PLoS ONE, 2010
Capsular polysaccharides are important factors in bacterial pathogenesis and have been the target of a number of successful vaccines. Francisella tularensis has been considered to express a capsular antigen but none has been isolated or characterized. We

A Narrative Review of the W, X, Y, E, and NG of Meningococcal Disease: Emerging Capsular Groups, Pathotypes, and Global Control

Microorganisms, 2021
Neisseria meningitidis, carried in the human nasopharynx asymptomatically by ~10% of the population, remains a leading cause of meningitis and rapidly fatal sepsis, usually in otherwise healthy individuals.

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-

Making the Case for Organ‐on‐Chip Platforms in Long‐Acting Therapeutics Development

Advanced Healthcare Materials, EarlyView.
LATs release drug from a tissue‐resident depot over weeks to months, improving adherence, but their development is hampered by preclinical models that cannot reproduce the coupled tissue processes, sustained release, local microenvironment change, interstitial transport, immune and foreign‐body responses, and clearance that govern depot performance in ...

The Biosynthesis of Capsular Polysaccharide in Aerobacter aerogenes

Journal of Biological Chemistry, 1971
Abstract Aerobacter aerogenes produces a capsular polysaccharide composed of tetrasaccharide repeating units containing galactose, mannose, and glucuronic acid in a molar ratio of 2:1:1. Particulate cell envelope fractions of the organism catalyze the incorporation of galactose, mannose, and glucuronic acid from their respective nucleotide derivatives ...
