Polysaccharides of type 6 Klebsiella

Water-extractable type 6 Klebsiella antigens were separated into a type 6-specific acidic polysaccharide and a neutral polysaccharide. The neutral polymer was devoid of type 6 activity although it was serologically active. The type 6-specific polymer contained fucose, glucose, and mannose, and pyruvic, galacturonic, and possibly glucuronic acids. The neutral polymer contained glucose, galactose, and mannose.
