志贺氏痢疾是我国常见病、多发病。根据我国主要流行型别特点，构建f侵袭表型阳性的福氏人来内氏双价痢疾菌苗。2株议价菌苗候选株生物表型及其稳定性研究结果：（1）O抗原表达，候选株能良好表达福氏Za及来内氏双价0抗原，用针对保护性表位单抗2E6及SSD3所做的FAS表明，福氏Za
Shigella dysentery is a common disease in our country, frequently-occurring disease. According to the characteristics of the major epidemic types in China, we constructed F-type Schistosoma japonicum bivalent dysentery vaccine with positive phenotype. The results showed that: (1) The expression of O antigen, the candidate strain can express well the Za and the Lewyz double-antigen 0 antigen, with the protective epitope mAb 2E6 And FAS made by SSD3 shows that Freescale’s Za
