The capsular antigen of Escherichia coli O9:K33:H-: a polysaccharide containing both pyruvate and O-acetyl groups.
The primary structure of the acidic capsular antigen of Escherichia coli O9:K33:H- was shown by glycose analysis, methylation analysis, and by 1D and 2D 1H and 13C NMR spectroscopy to be composed of branched tetrasaccharide repeating units with the structure: [formula: see text]
