Primary oral immunization of mice with a bacterial protein antigen genetically coupled to the A2 and B subunits of cholera toxin induced specific secretory immunoglobulin A and serum immunoglobulin G antibodies that persisted at substantial levels for at least 11 months. A subsequent single booster immunization did not further enhance the antibody responses. Long-term antibody persistence may be especially important in infections caused by common pathogens for which continuous immunity would be advantageous.
用与霍乱毒素A2和B亚基基因偶联的细菌蛋白抗原对小鼠进行初次口服免疫,可诱导产生特异性分泌型免疫球蛋白A和血清免疫球蛋白G抗体,这些抗体至少在11个月内持续保持较高水平。随后的单次加强免疫并未进一步增强抗体反应。对于常见病原体引起的感染,长期抗体持续存在可能尤为重要,因为持续免疫将具有优势。
