The O antigen polymer recovered from the reference strain for Stenotrophomonas (Xanthomonas or Pseudomonas) maltophilia serogroup O7, after mild acid hydrolysis of the lipopolysaccharide, was constructed from D-rhamnose. By means of chemical degradations and NMR studies, the repeating unit of the polymer was shown to be a linear trisaccharide with the structure →2)-α-D-Rhap-(1→3)-α-D-Rhap-(1→3)-α-D-Rhap-(1→. The same repeating unit is present in the common antigen of Pseudomonas aeruginosa and in O antigens from some pathovars of Pseudomonas syringae and a strain of Burkholderia (Pseudomonas) cepacia
