title: Nuclear-magnetic-resonance analysis of the capsular antigen of Actinobacillus pleuropneumoniae serotype 9. Its identity with the capsular antigen of Escherichia coli K62 (K2ab), Neisseria meningitidis serogroup H and Pasteurella haemolytica serotype T15.
abstract: The specific capsular antigen of Actinobacillus pleuropneumoniae serotype 9 was characterized by one-dimensional and two-dimensional high-field nuclear-magnetic-resonance methods, and by chemical analyses, as a teichoic-acid-type polymer of a repeating unit having the structure [formula: see text] The basic polymer structure is identical to capsular antigens of Neisseria meningitidis group H, Escherichia coli K62 (K2ab) and Pasteurella haemolytica serotype T15.
