The O-specific polysaccharide of Citrobacter braakii PCM1531 (serogroup O6) was isolated by mild acid hydrolysis of the lipopolysaccharide (LPS) and found to contain d-fucose, l-rhamnose, 4-deoxy-d-arabino-hexose and O-acetyl groups in molar ratios 2 : 1 : 1 : 1. On the basis of methylation analysis and 1H and 13C NMR spectroscopy data, the structure of the branched tetrasaccharide repeating unit of the O-specific polysaccharide was established. Using various serological assays, it was demonstrated that the LPS of strain PCM1531 is not related serologically to other known 4-deoxy-d-arabino-hexose-containing LPS from Citrobacter PCM1487 (serogroup O5) or C. youngae PCM1488 (serogroup O36). Two other strains of Citrobacter, PCM1504 and PCM1505, which, together with strain PCM1531, have been classified in serogroup O6, were shown to be serologically distinct from strain PCM1531 and should be reclassified into another serogroup.
