RESUMO
Several species of Salmonella, Citrobacter, and Arizona were examined for the presence of 3-amino sugars, which were isolated from lipopolysaccharide hydrolysates by cation exchange chromatography and identified by paper and cation exchange chromatography in several systems and by specific colorimetric procedures. 3-Amino-3,6-dideoxyglucose was identified in C. freundii 8090, C. freundii 869, S. halle, S. telaviv, S. dakar, S. wandsworth, and S. champaign; 3-amino-3,6-dideoxygalactose was found in S. tranoroa and Arizona 24. Evidence suggests that these 3-amino sugars occur in lipopolysaccharides as the N-acetyl derivatives. The composition of the lipopolysaccharides containing the 3-amino sugars was determined, and the lipopolysaccharides were compared serologically in order to correlate chemotypes with serotypes. The lipopolysaccharides containing 3-amino-3,6-dideoxyglucose reacted with serogroups 28 or 39; those containing 3-amino-3,6-dideoxygalactose were found to react with group 55 antisera. The preparation of a lipopolysaccharide from the phenol phase of the 44% aqueous phenol extraction procedure is also reported.
