Correspondence Response of Treponema pallidum Particle Agglutination Test Titers to Treatment of Syphilis

on the serological response to treatment of syphilis according to disease stage and human immunodeficiency virus (HIV) status [1]. In particular, we ana-lyzed the course of the Venereal Disease Research Laboratory (VDRL) and a specific immunoglobulin M capture enzyme-linked immunosorbent assay test (Pathozyme-IgM) in 264 patients.
