✦ Synopsis

The O-specific polysaccharide of S. atiz~~~ae 021 was found to contain 2-acetamido-2deoxy-o-glucose, 2-acetamidino-2,6-dideoxy-L-galactose, N-acetylneuraminic acid, and Oacetyl groups. On the basis of 'H and 13C NMR studies of the intact and O-deacetylated polysaccharide and oligosaccharide fragments obtained by solvolysis with anhydrous hydrogen fluoride, partial methanolysis and partial hydrolysis, it was concluded that the O-specific polysaccharide has the following structure: + 3)+-L-FucpN-(1 --j 3)-O-D-GlqpNAc-(1 -+ 7)-c+Neup5Ac-(2 -+ 2 I 6 I CH,C=NH M 70% OAc * Corresponding author.
