    A phosphorylated 3-deoxy-manno-octulosonic acid (KDO) was released from the lipopolysaccharide (LPS) of the deep rough mutant (Rb+169) of Haemophilus influenzae by acid hydrolysis. Both phosphorylated and dephosphorylated KDO, produced by treatment with alkaline phosphatase, were identified by gas chromatography-mass spectrometry after trimethylsilylation. This technique provides a rapid and reliable method for the identification of phosphorylated KDO in LPS.
