Bacterial Extracellular Polysaccharides [PDF]

, 2011
Extracellular polysaccharides are as structurally and functionally diverse as the bacteria that synthesise them. They can be present in many forms, including cell-bound capsular polysaccharides, unbound "slime", and as O-antigen component of lipopolysaccharide, with an equally wide range of biological functions. These include resistance to desiccation,

Bacterial Polysaccharide Capsules

2010
A common feature of many bacteria is the expression of a layer of extracellular polysaccharide usually organised into a discrete structure termed the capsule. The expression of a capsule results in the coating of the bacterium in a hydrated shell of high molecular weight polysaccharide molecules that mediate interactions between the bacterial cell and ...

Bacterial extracellular polysaccharides

Canadian Journal of Microbiology, 1988
The synthesis of extracellular polysaccharides has been recognized in certain bacterial cultures since the 1880s. It is now apparent that a wide range of bacteria produce these polymers and an equally wide range of chemical structures are possible.

Function of Bacterial Polysaccharides in the Soil

Nature, 1946
MOST aerobic micro-organisms such as B. subtilis, B. megatherium, Leuconostoc species, Rhizobia, etc., are capable under favourable cultural conditions of producing highly viscous polysaccharides either as heavy capsular material or as extracellular products.

Components of Bacterial Polysaccharides

1990
Publisher Summary This chapter explains all the known components of bacterial polysaccharides, except the amino acids in peptidoglycans that had been reported in the literature before 1989. Five pentoses—namely, D -ribose, D - and L -arabinose, and D - and L -xylose, have been found in the hydrolyzates of bacterial polysaccharides. Six of the 18

Adsorption of Bacterial Polysaccharides to Erythrocytes

Nature, 1948
WE recently reported that saline extracts of smooth strains of Haemophilus influenzae (Type b) contain a substance adsorbable to erythrocytes1. Cells treated with such extracts are agglutinated by type-specific antisera. A sample of the type-specific polysaccharide, prepared by the method of Dingle and Fothergill2, absorbed from immune sera their power

Bacterial Polysaccharides, Endotoxins, and Immunomodulation

1992
These 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.

Immunology of bacterial polysaccharide antigens

Carbohydrate Research, 2003
Carbohydrates 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.

Bacterial capsular polysaccharides and exopolysaccharides

2010
Bacteria 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 ...
