Sera from 225 patients who 20 years earlier had been infected with endemic syphilis and adequately treated with penicillin (PAM 4.8-6 megaunits) at various stages of the disease, were investigated for serological reactivity by the fluorescent treponemal antibody absorption (FTA-ABS), treponemal haemagglutination, and Venereal Diseases Research Laboratory tests. Specific antibodies were found in a large percentage of cases and their presence may be assumed to depend on persisting specific antigen which stimulates their synthesis.
对225名患者的血清进行了研究，这些患者在20年前感染了地方性梅毒，并在疾病的各个阶段用青霉素（480 - 600万单位）进行了充分治疗，通过荧光密螺旋体抗体吸收试验（FTA - ABS）、密螺旋体血凝试验和性病研究实验室试验检测其血清学反应性。在很大比例的病例中发现了特异性抗体，并且可以认为它们的存在取决于持续刺激其合成的特异性抗原。
