Specific antibody responses in the lower respiratory tract of human subjects to orally administered Salmonella typhi Ty21a are reported. These responses, predominantly of the immunoglobulin G class, were determined to be a transudate from serum. These results were supported by the similarity in responses to parenteral administration of heat-killed typhoid vaccine. Specific immunoglobulin A antibody was a poor contributor to the respiratory antibody response to either vaccine.
据报道,人类受试者下呼吸道对口服伤寒沙门氏菌Ty21a的特异性抗体反应。这些反应主要为免疫球蛋白G类,被确定为血清渗出液。对肠外注射热灭活伤寒疫苗的反应相似,支持了这些结果。特异性免疫球蛋白A抗体对两种疫苗的呼吸道抗体反应贡献不大。
