Chlamydia trachomatis infections in Japan.

Several studies were conducted to determine the incidence of Chlamydia trachomatis infections in various populations, including pregnant women, prostitutes, men with nongonococcal and gonococcal urethritis, women with nongonococcal and gonococcal cervicitis, and patients with the urethral syndrome. Levels of IgG and IgA were also determined. The efficacy of doxycycline in the treatment of chlamydial urethritis was evaluated in 106 patients. After two weeks of treatment, 98% of the infections were cured. Only one patient had to continue therapy for three weeks to eradicate the C trachomatis.
