经细菌载体投递的基因融合肽口服免疫对热稳定性大肠杆菌肠毒素的粘膜保护作用肠毒素是大肠杆菌引起腹泻的重要原因。大肠杆菌除了产生分子量较高、热不稳定的肠毒素（ＬＴ）外，还能产生一种分子量较低、热稳定肠毒素（ＳＴ），因其分子量低，免疫原性也就相对较差，但将... Oral administration of gene fusion peptides delivered by bacterial vectors Oral immunization of thermostable E.coli enterotoxins Enterotoxins are an important cause of E. coli-induced diarrhea. In addition to the higher molecular weight, heat-labile enterotoxin (LT), Escherichia coli produces a lower molecular weight, thermostable enterotoxin (ST) because of its lower molecular weight and its relatively poor immunogenicity, But will ...
