The structure of the Klebsiella K31 capsular polysaccharide has been elucidated by periodate oxidation, methylation analysis, characterization of oligosaccharides obtained by partial, acid hydrolysis, and proton magnetic resonance. The polymer consists of pentasaccharide repeating-units having the following structure (1).
