title: Prevalence of concurrent Chlamydia trachomatis infections among men with gonococcal urethritis in Lusaka.
abstract: The prevalence of Chlamydia trachomatis infections among male patients with gonococcal urethritis in the sexually transmitted diseases (STDs) clinic at UTH, Lusaka, was determined by two methods to be around 4.7%. Methods used were specific for C. trachomatis (Syva Microtrak), and second isolation of C. trachomatis. The results indicate that with a prevalence rate of 4-7% for concurrent gonococcal and chlamydial infection, it is not financially or medically practical to treat all cases of gonorrhoea in Zambia for possible chlamydial infection, as is advocated in some countries. The findings further suggest that the commercially available Syva Microtrak test should probably be considered positive when one or two monoclonal-stained elementary bodies are seen, rather than ten, to avoid false-negative results.
