title: Structure of the O-chain of the lipopolysaccharide of Pasteurella haemolytica serotype T3.
abstract: Cell-wall lipopolysaccharide isolated from Pasteurella haemolytica serotype T3 using the phenol-water extraction procedure was shown to be an S type lipopolysaccharide by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Hydrolysis with mild acid afforded a lipid-free, antigenic O-chain polysaccharide. On the basis of one- and two-dimensional 1H and 13C nuclear magnetic resonance studies, in conjunction with microanalytical chemical methods, the O-polysaccharide was determined to be a linear polymer of a disaccharide repeating unit having the structure.
