We investigated the infection rate of Chlamydia trachomatis in sexual partners who had pregnani wives with C. trachomatis diagnosed by means of serum-antibody test (Ipazyme®) or antigen tes1 (Chlamydiazyme®, IDEIA-chlamydia®). Antibody-positive rate was 60.4%(90/149 cases), and antigen-positive rate was 7.4% 11/149 cases All cases with Chlamydial antigen had anti-Chlamydial antibody. Eleven cases with Chlamydial antigen had no symptom of urethritis. Among these cases, eigh cases had abnormal laboratory findings. However, the other three cases who had no abnormal findini were careers of C. trachomatis.
