[Chlamydia trachomatis in patients with genital contact infections in Austria--studies of 3,367 patients].

In order to evaluate the epidemiological importance of Chlamydia trachomatis (C. trachomatis) as a genital microorganism, data were obtained from 3,367 patients with sexually transmitted diseases in Vienna and analyzed by computer-assisted methods. C. trachomatis was cultured in 26.1% of 2,594 patients investigated for the first time. The microorganism was found more often in male patients (31.3%) than in female patients (21%). 32.2% of positive Chlamydia cultures were obtained from patients with non-gonococcal urethritis (NGU) and 64% from postgonococcal urethritis (PGU) patients. A high coincidence with Neisseria gonorrhoeae (N. gonorrhoeae) was detected in males (31.2%) and females (43.5%). Data on Mycoplasma hominis (M. hominis), and Ureaplasma urealyticum (U. urealyticum) show that, in contrast to the low incidence of M. hominis and U. urealyticum in males, the organisms were found predominantly in females.
