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 ‐Rha p ‐(1→3)‐α‐ d ‐Rha p ‐(1→3)‐α‐ d ‐Rha p ‐(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 .
