Schematic diagram of the polysaccharide anchored onto phospholipids of the external bacterial membrane forming the K1 capsular lyso-PG raft. A single type of K1 capsule anchored on lyso-PG is shown to form a raft. The capsular brush rafts created at the polar and the equatorial regions (the dashed circle/rectangle shows the different regions of the capsular brush rafts) and then spread out to cover the whole bacterial surface.
