The structure of the O-antigen polysaccharide from Escherichia coli O-149 has been investigated; methylation analysis, partial hydrolysis with acid, and n.m.r. spectroscopy were the principal methods used. It is concluded that the polysaccharide is composed of trisaccharide repeating-units having the following structure. [formukla; see text] The absolute configuration at the acetalic carbon atom of the pyruvic acid residue is S.
