[The rate of detecting Chlamydia in male homosexuals with syphilis].

A total of 159 homosexuals suffering from various forms of syphilis, aged 17 to 71, were screened for chlamydial antigen with the use of fluorescent monoclonal antibodies. Asymptomatic urogenital chlamydiosis was detected in 33 of 107 (30.8 percent) homosexual syphilitics. In 52 patients the material was collected simultaneously from the throat, urethra, and rectum; Chlamydia were detected in 71.2 percent of these.
