The authors examined using the polymerase chain reaction (PCR) more than 2700 gynaecological patients for the presence of Ch. tracheomatis. The patients were mostly from Bratislava and surroundings. The material used were cervical smears or morning urine. The most frequent diagnoses associated with Chlamydia infection were adnexitis (38%), cervicitis (22%), pelvic pain (9%), sterility (9%), cystitis and ureteritis (3%) abortus imminenes (4%) partus prematurus imminenes (9%). There was a marked seasonal character of chlamydias with the peak during the summer period. The mean age of the patients was 29.2 years and thus the assumed higher incidence of younger age groups was not confirmed. PCR proved to be an accurate, reliable and perspective method for the detection of Ch. trachomatis in Slovak gynaecological patients.
