  The structure of the capsular polysaccharide isolated from Klebsiella K68 bacteria has been elucidated by both chemical and spectroscopic methods. The structure is of the "3 + 1" type, similar in pattern to the structures of the polysaccharides of Klebsiella K11 and K57, having a single branch point on the uronic acid. The polysaccharide is shown to consist of the following repeating unit: (Formula: see text).
