1D and 2D NMR spectroscopy revealed that the O - specific polysaccharide ( OPS ) of A . bestiarum K296 consists of a branched tetrasaccharide repeating unit containing two 6 - deoxy - l - talose ( 6dTalp ) , one Manp and one GalpNAc residues ; thus , it is similar to that of the OPS of A . hydrophila AH - 3 ( serotype O34 ) in both the sugar composition and the glycosylation pattern .
