Purification and immunochemical properties of Escherichia coli B polysaccharide cross-reacting with Salmonella typhi Vi antigen: preliminary evidence for cross-reaction of the polysaccharide with Escherichia coli K1 antigen.

RESUMO
An acidic polysaccharide of Escherichia coli B was isolated by a mild procedure and purified to homogeneity. The polysaccharide was found to react in Salmonella typhi Vi antisera and E. coli K1 antisera. Serological analysis and preliminary chemical characterization of the polysaccharide indicated that it is an aminouronic acid polymer which, although not structurally identical to either Vi or K1, appears more like the Vi antigen, both immunochemically and chemically.
