沙门氏杆菌属及其检验

相。对沙门氏杆菌O抗原成分的化学研究，证明是由多糖构成的。这种多糖以半乳糖、甘露糖和鼠李糖的重复单位为基本结构。毒素与其它肠道细菌的情况一样，是内毒素，鼷鼠致死量约为0.5毫克左右，是一种多糖磷脂质的复合体。鸟、人、猪对许多菌都有较高的敏感性，但症状上与肠伤寒、副伤寒、食物中毒（主要是肠炎沙门氏菌和鼠伤寒沙门氏菌）一样，有各种不同的程度。治疗上氯霉素最有效。     　　沙门氏菌属（Salmonella）是一大群寄生于人类和动物肠道内生化反应和抗原构造相似的革兰氏阴性杆菌统

Characterization of Glycosaminoglycans by Capillary Electrophoresis

to a D-glucosamine (either N -sulfo or N -acetyl-d -glucosamine) residue. Both saccharide residues can be O -sulfonated at a variety of different positions, making these glycosaminoglycans structurally complex. Hyaluronic acid contains a simple repeating

Synthesis of Azido-Functionalized Carbohydrates for the Design of Glycoconjugates

of the carbohydrate derivative, or attached to a spacer arm. We describe here the syntheses of 2,3,4,6-tetra-O -acetyl-β-d -glucopyranosyl azide as well as 1-azido-3,6-dioxaoct-8-yl 2,3,4,6-tetra-O -acetyl-β-d -galactopyranoside and 1-azido-3,6-dioxaoct-8-yl
