The structure of the O-antigen of Actinobacillus pleuropneumoniae serotype 12 was determined by 1D and 2D NMR spectroscopic methods, methylation analysis, and partial hydrolytic degradation. The O-polysaccharide was shown to consist of a trisaccharide repeating unit having the structure [formula in text].
