Abstract

Both a neutral and an acidic polymer have been isolated from a lipopolysaccharide extract of the reference strain for Serratia marcescens serogroup O22. The neutral polymer has a linear structure with the repeating unit shown. The same tetrasaccharide unit also forms the backbone of the branched neutral polymer isolated from the reference strain for serogroup O10, which cross-reacts strongly with O22. ----2)-alpha-L-Rhap-(1----2)-alpha-L-Rhap-(1----3)-alpha-L-+ ++Rhap-(1----3)-alpha- D-GlcpNAc-(1----

摘要

已从粘质沙雷氏菌O22血清群参考菌株的脂多糖提取物中分离出一种中性聚合物和一种酸性聚合物。中性聚合物具有所示重复单元的线性结构。相同的四糖单元也是从O10血清群参考菌株中分离出的支链中性聚合物的主链，该聚合物与O22有强烈交叉反应。----2)-α-L-鼠李糖-(1----2)-α-L-鼠李糖-(1----3)-α-L-+ ++鼠李糖-(1----3)-α-D-氨基葡萄糖-(1----
