| Abstract: | Abstract Lipopolysaccharide (LPS) was isolated from a strain of Aeromonas hydrophila which had displayed serological, bacteriophage attachment and virulence properties similar to those found in strains of Aeromonas salmonicida . The structure of the O-antigen was determined and had many points of similarity with that previously elucidated for the O-antigen of A. salmonicida . Methylation analysis, chromium trioxide oxidation and 1H-n.m.r. were used to confirm that the repeating unit of the O-chain had the following structure:
