Bacterial Polysaccharides, Endotoxins, and Immunomodulation
1992These studies show that at least some--though certainly not all--of the adjuvant effects of LPS and its derivatives can be attributed to its ability to eliminate the inhibitory effects of Ts which are activated during the course of a normal immune response.

Biopolymers, 1978
AbstractThe optical activity of the Klebsiella capsular polysaccharides of serotypes K1, K5, K6, K8, K11, K56, and K57 has been studied in aqueous solution. Measurements of ORD in the range 185–450 nm reveal anomalous ORD with Cotton effects near λ0 = 195nm. The results are evaluated quantitatively according to hte Moffitt‐Yang and the Drude equations.

Immunology of bacterial polysaccharide antigens
Carbohydrate Research, 2003Carbohydrates in the form of capsular polysaccharides and/or lipopolysaccharides are the major components on the surface of bacteria. These molecules are important virulence factors in many bacteria isolated from infected persons. Immunity against these components confers protection against the disease.

Uptake of metals by bacterial polysaccharides
Journal of Applied Bacteriology, 1993J.L. GEDDIE AND I.W. SUTHERLAND. 1993. The binding of cations by a range of bacterial polysaccharides was examined. Comparison of native and deacetylated polymers indicated the influence of polysaccharide acetylation on ion uptake and selectivity. The effects of temperature and pH on ion uptake were also examined.

Capillary Electrophoresis of Bacterial (Lipo)Polysaccharides [PDF]
, 2010 Lipopolysaccharides (LPSs) are major components of the outer membrane of gram-negative bacteria, and, along with some acidic polysaccharides, are important macromolecules belonging to bacteria. The recent emergence of modern analytical tools for their study has produced a virtual explosion in the field of glycomics.

Involvement of Bacterial Polysaccharides in Plant Pathogens
Annual Review of Phytopathology, 1995Virulence of phytopathogenic bacteria is often correlated with their ability to produce extraceUular polysaccharides (EPSs). The composition and amount of lipopolysaccharide O-antigens and low molecular weight, cell-associated 13linked glucans may also affect virulence of Gram-negative pathogens. For a few species of Agrobacterium. Clavibacter, Erwinia.

Conformational investigation on the bacterial polysaccharide xanthan
Carbohydrate Research, 1979The conformation of xanthan has been investigated as a function of temperature, ionic strength, and polymer concentration. A reversible transition induced by temperature is demonstrated; the melting temperature (TM) is directly correlated to the total ionic-strength and is independent of the polymer concentration.

Visualization of the Bacterial Polysaccharide Capsule
1990The highly hydrated capsule of E. coli strains is composed of a large number of polysaccharide fibers of which the thinnest measure about 2 nm in width. The fibers may span the entire distance from the outer membrane to the outer rim of the capsule and show a propensity to associate with each other to form thicker filaments. Presence of thick filaments

Bacterial capsular polysaccharides and exopolysaccharides
2010Bacteria often produce an external layer of polysaccharides, characterized by a definite primary structure, which in turn is responsible for sometimes remarkable physicochemical properties. Although the number of monosaccharides which constitute the polymers is rather low, the great number of different polysaccharides defined up to now shows the ...
