Abstract
The aqueous-phase lipopolysaccharide isolated from Pasteurella haemolytica serotype T10 cells by the phenol-water extraction method was found to be S-type lipopolysaccharide which possessed O-antigenic polysaccharide chains composed only of D-galactose residues. Structural analysis of the O-polysaccharide, using a combination of 1D and 2D 1H- and 13C-n.m.r. methods, led to the identification of the disaccharide repeating-unit as [----3)-alpha-D-Galp-(1----3)-beta-D-Galf-(1----]n. The serological cross-reactivity between P. haemolytica serotypes T4 and T10 can now be related to the structural similarity of the antigenic LPS O-polysaccharides.Entities:
