Abstract

Rabbits were immunized over a 32-week period with a total of 450 micrograms of purified Treponema pallidum endoflagella. As measured by enzyme-linked immunosorbent assay, sera from immunized rabbits had antiendoflagellar antibody titers that were fivefold greater than titers of sera from infected immune rabbits and patients with secondary disease. Sera from all immunized animals possessed complement-dependent treponemicidal activity as measured by in vitro immobilization. Immunized animals challenged with virulent T. pallidum were not protected from symptomatic infection but showed an altered course of lesion development.

摘要

在32周的时间里,给兔子总共注射450微克纯化的梅毒螺旋体轴丝。通过酶联免疫吸附测定法测量,免疫兔子的血清中抗轴丝抗体滴度比感染免疫兔子和二期疾病患者血清的滴度高五倍。通过体外固定化测量,所有免疫动物的血清都具有补体依赖性杀梅毒螺旋体活性。用强毒梅毒螺旋体攻击的免疫动物没有免受症状性感染,但病变发展过程有所改变。
