Immunity to challenge with Salmonella typhimurium (strain SR-11) was studied in NIH/NMRI Swiss mice. Viable organisms induced the best protection, but ribosomes were the best immunogen of the subcellular fractions. Antigens with lower concentrations of protein did not induce protection as well as antigens which had higher concentrations of protein. Acrylamide gel electrophoresis of the SR-11 subcellular components, fractionation, and differential staining of the gel columns indicated that the immunogen is a high-molecular-weight glycoprotein or mucopolysaccharide.
在NIH/NMRI瑞士小鼠中研究了对鼠伤寒沙门氏菌(菌株SR-11)攻击的免疫力。活的生物体诱导出最佳保护作用,但核糖体是亚细胞组分中最佳的免疫原。蛋白质浓度较低的抗原诱导的保护作用不如蛋白质浓度较高的抗原。对SR-11亚细胞组分进行丙烯酰胺凝胶电泳、凝胶柱分级分离和差异染色表明,免疫原是一种高分子量糖蛋白或粘多糖。
