Study of sera from 69 patients with untreated or inadequately treated latent syphilis revealed that immunoglobulin (Ig)G antibodies made up the bulk of the fluorescent treponemal antibody-absorption (FTA-ABS)-test reactivity found in the sera. IgM and IgA antibodies also contributed in some cases. Venereal Disease Research Laboratory slide-test reactivity was found in both 19 and 7S serum fractions, whereas Treponema pallidum immobilization-test reactivity was found mainly in the 7S fraction.
对 69 例未经治疗或治疗不充分的潜伏梅毒患者的血清进行研究发现，在血清中发现的荧光密螺旋体抗体吸收（FTA-ABS）试验反应性主要由免疫球蛋白（Ig）G 抗体组成。在某些情况下，IgM 和 IgA 抗体也有贡献。性病研究实验室玻片试验反应性在 19 血清和 7S 血清部分中均有发现，而密螺旋体苍白密螺旋体固定试验反应性主要在 7S 部分发现。
