Capsular polysaccharides of Cryptococcus neoformans. 1984

A K Bhattacharjee, and J E Bennett, and C P Glaudemans

Polysaccharides of Cryptococcus neoformans are considered to have a role in the virulence of this encapsulated fungus. The structure has been determined for the most abundant polysaccharide, a glucuronoxylomannan of varying xylose and ester content. The structural complexity of the capsular material increases from serotype D to A to B to C, but even for the simplest capsule (type D), the immunodeterminants seem to occur only on the side chains. The interactions of some of these groups with antibodies is discussed.
