Comparison of polyacrylamide gel electrophoretic protein profiles of four isogenic sets of virulent phase I Sh. sonnei strains and their avirulent phase I cells revealed no differences in outer membrane protein composition between virulent and avirulent derivatives. However, significant qualitative and quantitative differences were found in composition of major outer membrane proteins between strains of different origin. All four strains tested contained one major protein of 33K. This protein was susceptible to proteolytic enzymes and was found to be heat modifiable. Other major proteins of 35K and 37K present in three strains and 36K present in one strain were identified as peptidoglycan associated proteins.
对四组同基因的I相有毒力宋内志贺氏菌菌株及其I相无毒力细胞进行聚丙烯酰胺凝胶电泳蛋白质谱比较，结果显示有毒力和无毒力衍生物之间的外膜蛋白组成没有差异。然而，不同来源菌株之间的主要外膜蛋白组成存在显著的定性和定量差异。所有测试的四株菌株都含有一种33K的主要蛋白。该蛋白易受蛋白水解酶作用，且发现其可被热修饰。在三株菌株中存在的35K和37K以及在一株菌株中存在的36K的其他主要蛋白被鉴定为肽聚糖相关蛋白。
