The O-specific polysaccharide of Proteus penneri strain 34 was studied using 1H and 13C NMR spectroscopy, including 2D COSY, TOCSY, NOESY and H-detected HMQC experiments. The following structure was established which is unique among the known structures of Proteus O-antigens:

-4)bDGalpNAc(1-4)bDGalp(1-4)bDGlcp(1-3)bDGalpNAc(1-

Accordingly, no cross-reaction was observed between P. penneri O34 antiserum and O-antigens of other Proteus strains. Therefore, the strain studied shoud belong to a new Proteus serogroup O65.
