The present invention relates to a synthetic oligosaccharide of general formula (I): T*-[(—U x+4 —U x+3 —U x+2 —U x+1 —U x ) m —(V x+2 —V x+1 —V x ) 1-m -T-O-L-E that is related to Klebsiella pneumoniae serotype O3, O3b and/or O5 lipopolysaccharide and conjugate thereof. Said synthetic oligosaccharide, said conjugate and pharmaceutical composition containing said synthetic oligosaccharide or said conjugate are useful for prevention and/or treatment of diseases associated with Klebsiella pneumoniae . Furthermore, the synthetic oligosaccharide of general formula (I) is useful as marker in immunological assays for detection of antibodies against Klebsiella pneumoniae serotype O3, O3b and/or O5 bacteria. |
