Abstract

The O antigen polymer recovered from the reference strain for Stenotrophomonas (Xanthomonas or Pseudomonas) maltophilia serogroup O7, after mild acid hydrolysis of the lipopolysaccharide, was constructed from D-rhamnose. By means of chemical degradations and NMR studies, the repeating unit of the polymer was shown to be a linear trisaccharide with the structure -->2)-alpha-D-Rhap-(1-->3)-alpha-D-Rhap-(1-->3)-alpha-D-R hap-(1-->. The same repeating unit is present in the common antigen of Pseudomonas aeruginosa and in O antigens from some pathovars of Pseudomonas syringae and a strain of Burkholderia (Pseudomonas) cepacia.

摘要

嗜麦芽窄食单胞菌（嗜麦芽黄单胞菌或嗜麦芽假单胞菌）血清群O7参考菌株经轻度酸水解脂多糖后回收的O抗原聚合物由D-鼠李糖构成。通过化学降解和核磁共振研究表明，该聚合物的重复单元是一种线性三糖，结构为 -->2)-α-D-鼠李糖-(1-->3)-α-D-鼠李糖-(1-->3)-α-D-鼠李糖-(1-->。铜绿假单胞菌的共同抗原以及丁香假单胞菌某些致病变种和洋葱伯克霍尔德菌（假单胞菌）菌株的O抗原中也存在相同的重复单元。
