title: Urethritis in white men--a microbiological appraisal.
abstract: The incidence of infections with Neisseria gonorrhoeae, Chlamydia trachomatis and mycoplasmas has been assessed in White men with urethritis who were attending a Johannesburg clinic for sexually transmitted diseases. Infection with N. gonorrhoeae was demonstrated in 54% of 212 patients with urethritis. C. trachomatis was isolated from 37% of patients with non-gonococcal urethritis, and from 25% with proven gonococcal infection. Although T-mycoplasmas were isolated significantly more often from patients with urethritis (41%) than from controls (23%) (P less than 0,05) their role in the aetiology of urethritis is uncertain.
