The core oligosaccharide structure of the in vivo derived rough phenotype of Aeromonas salmonicida subsp. salmonicida was investigated by a combination of compositional, methylation, CE-MS and one- and two-dimensional NMR analyses and established as the following: [GRAPHICS] where R =alpha-D-Galp-(1 -> 4)-beta-D-GalpNAc-(1 -> or alpha-D-Galp-(1 -> (approx. ratio 4:3). Comparative CE-MS analysis of A. salmonicida subsp. salmonicida core oligosaccharides from strains A449, 80204-1 and an in vivo rough isolate confirmed that the structure of the core oligosaccharide was conserved among different isolates of A. salmonicida.
