[The prevalence of C. trachomatis genitourinary tract infection in 1986-1993].

The study comprised 7224 patients from Lower Silesia District, 3576 women and 3648 men, at age 18-69 yrs. Urethral and endocervical specimens were tested for Chlamydia trachomatis using culture method (on McCoy cells treated with cycloheximid), immunofluorescent technique (Chlamyset-Orion Diagnostica) or immunoenzymatic assay (Chlamydiazyme-Abbott). In the examined population chlamydial infection was found in prevalence among 20-40 yrs old patients. Symptomatic infection was observed in 97.3%, asymptomatic in 2.7%. Basing on the laboratory tests results chlamydiosis was diagnosed in 1393 (19.2%) patients, 658 (47.2%) women and 735 (52.7%) men. The highest percentage (25.7%) of the infected people was noticed in 1986, the lowest in 1991 (10.6%). Despite the general declining trend, every second year a small rising in number of C. trachomatis infection was regularly observed.
