摘要：
The antigenic O-polysaccharide component of the lipopolysaccharide produced by Escherichia coli serotype O71:H12 was analyzed by chemical composition, nuclear magnetic spectroscopy, and Smith-type periodate oxidation methods. It was determined to be a partially O-acetylated unbranched polymer of a repeating tetrasaccharide unit composed of L-rhamnose. D-galactose, 2-acetamido-2-deoxy-D-galactose, and 3-acetamido-3-deoxy-D-quinovose (1:1:1:1) residues having the following structure: [GRAPHICS] .
